To keep up, an ICP-OES system must maintain plasma stability, reduce drift, and minimize downtime.</p><p>The iCAP PRO ICP-OES is built with design features that support robust, reliable operation across demanding sample types.</p><h3><strong>Optimized vertical torch designed for extended stability and uptime</strong></h3><p>The iCAP PRO ICP-OES vertical torch design optimizes airflow within the torch box to support a stable, matrix-tolerant plasma. This helps reduce deposition on the torch and injector, which can support longer, more stable analytical runs.</p><p><strong>For ICP analysts, the benefits are clear:</strong></p><ul><li><strong>Reduced signal drift</strong></li><li><strong>Fewer sample failures and reruns</strong></li><li><strong>Less matrix buildup on key components</strong></li><li><strong>Reduced maintenance-related downtime</strong></li><li><strong>Long-term stability and reliability when analyzing challenging samples</strong></li></ul><p>If cleaning is needed, the passivated aluminum torch box can be removed with just three screws, making maintenance more straightforward.</p><h3><strong>Purged Optical Path for efficient UV transmission</strong></h3><p>The iCAP PRO ICP-OES also uses a <strong>Purged Optical Path, or POP, interface</strong> to help maintain efficient light transmission from the plasma to the spectrometer. Low-flow argon purge gas exits through ceramic axial and radial POP nozzles, creating a protected optical path that helps reduce UV absorption by air and helps prevent plasma byproducts, dust, soot, and sample material from reaching the optical system.</p><p>This is especially important for ICP-OES analysis because many critical emission lines are in the UV range.</p><p><strong>Key benefits include:</strong></p><ul><li><strong>Improved UV sensitivity.</strong></li><li><strong>Lower detection limits for important elements such as arsenic, selenium, and lead.</strong></li><li><strong>Reduced contamination of the optical interface.</strong></li><li><strong>No need for a separate shear gas supply or air compressor.</strong></li><li><strong>Simplified operation and lower running complexity.</strong></li></ul><h3><strong>Mirror protection for long-term optical performance</strong></h3><p>The intense ultraviolet light produced by the plasma can gradually degrade optical mirrors over time. To help protect the optical system, the iCAP PRO ICP-OES uses an automated beam blocker that shields mirrors from unnecessary UV exposure when measurements are not being taken.</p><p><strong>This helps support:</strong></p><ul><li><strong>Long-term optical stability.</strong></li><li><strong>Reduced mirror wear.</strong></li><li><strong>Lower maintenance requirements.</strong></li></ul><h3><strong>High-efficiency optics and detection for confident results</strong></h3><p>The iCAP PRO Series ICP-OES combines a compact, high-efficiency optical design with proprietary <strong>Charge Injection Device, or CID, detector technology</strong> to help maximize sensitivity, speed, and confidence in results.</p><p>The optimized optical path helps transmit more light from the plasma to the detector, while the 5th generation CID821 detector captures high-quality spectral information across the wavelength range with more than 2 million pixels and smaller pixel size than in the previous iCAP platform.</p><p><strong>Together, these technologies support:</strong></p><ul><li><strong>Efficient light transmission</strong></li><li><strong>Improved sensitivity</strong></li><li><strong>Better spectral resolution</strong></li><li><strong>Faster analysis</strong></li><li><strong>More confident results in complex matrices</strong></li></ul><h3><strong>The CID detector advantage: more spectral detail, less compromise</strong></h3><p>In real-world ICP-OES analysis, a single sample can contain trace-level analytes that produce weak signals and major matrix elements that produce very intense emission lines. The detector must manage both at the same time.</p><p>That is where CID detector technology provides a significant advantage.</p><p>The iCAP PRO ICP-OES CID821 smaller pixel size and high pixel density help improve physical separation between adjacent wavelengths, giving analysts more flexibility when choosing emission lines and background correction points. This also makes it easier to resolve trace analytes from nearby matrix lines, such as trace molybdenum in a tungsten matrix or trace lead in high-concentration copper.</p><p><strong>For the ICP-OES user, this means:</strong></p><ul><li><strong>Better peak separation</strong></li><li><strong>Easier background correction</strong></li><li><strong>Reduced spectral overlap</strong></li><li><strong>Less reliance on correction strategies and mathematical equations</strong></li><li><strong>Greater confidence in complex sample analysis.</strong></li></ul><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_How_to_Simplify_ICP_OES_Analysis_Method_Development_High_Matrix_Samples_and_Daily_Operation_3_e3e0cb27d9.jpg" alt="Thermo Fisher Scientific: How to Simplify ICP-OES Analysis: Method Development, High Matrix Samples, and Daily Operation" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_How_to_Simplify_ICP_OES_Analysis_Method_Development_High_Matrix_Samples_and_Daily_Operation_3_e3e0cb27d9.jpg 245w," sizes="100vw" width="768" height="357"></p><h3><strong>Why anti-blooming matters in ICP-OES</strong></h3><p>Instruments have advanced significantly from classical Paschen-Runge, or Rowland Circle, spectrometers that used individual photomultiplier tubes, or PMTs, positioned at fixed wavelengths. While effective, these systems required larger optical layouts and offered less flexibility because each PMT was dedicated to a specific emission line. The transition to solid-state chip detectors, known as Charge Transfer Devices, or CTDs, helped make ICP-OES instruments more compact, flexible, and information-rich by enabling many wavelengths to be captured across a detector array. This shift supported faster multi-element analysis, easier wavelength selection, improved method development, and access to full-spectrum data from a smaller instrument platform. The two primary CTD technologies used in ICP-OES are the Charge-Coupled Device, or CCD, and the CID.</p><p>In CTD detector-based ICP-OES, photons from emission lines are converted into electrical charge within individual pixels. When an intense emission line saturates a detector region, excess charge can spread into neighboring pixels, an effect known as <strong>blooming.</strong> In CCD detectors, where charge is shifted pixel by pixel across the chip during readout, blooming can distort nearby weaker signals and lead to overestimation of their intensity.</p><p>The CID detector within the iCAP PRO ICP-OES works differently. In a CID, each pixel is an independent site with its own set of electrodes. The electrical charge generated by incoming light is collected and stored directly inside that specific pixel. If a pixel fills to capacity, the excess charge drains into the underlying silicon substrate rather than spilling into neighboring pixels. Pixels are addressed individually and read without shifting charge across the array, helping contain intense signals. In this way, <strong>CID detectors are inherently anti-blooming.</strong></p><p>For analysts, anti-blooming helps protect trace-level analyte peaks near strong matrix emission lines. This can reduce the need to choose less sensitive wavelengths, add extra dilutions, or rely on additional correction strategies that may increase method complexity.</p><p>Additionally, because the charge doesn’t have to move across the chip to be read (unlike a CCD), a CID can perform <strong>Non-Destructive Readout (NDRO)</strong> where the CID detector can measure the charge in an individual pixel without emptying it. For ICP-OES analysis, this provides two important benefits.</p><ul><li>First, weak emission lines can be integrated for a longer time to collect more signal.</li><li>Second, bright emission lines can be monitored during the exposure and read before they approach saturation.</li></ul><p>In practical terms, NDRO helps the CID detector capture weak trace-level signals more effectively while managing intense matrix lines — improving signal-to-noise ratio resulting to better sensitivity, extending dynamic range, and leading to more confident trace-level results.</p><p>The blooming effect experienced in CCD detectors can be minimized by setting integration times, segmenting the detector, or by adding anti-blooming or overflow drains. These approaches can help reduce the impact of very intense emission lines on weaker trace-level signals and reduce blooming, but they are mitigation strategies rather than the inherent pixel-level readout advantage of CID technology.</p><h3><strong>Intelligent Full Range and enhanced UV modes</strong></h3><p>The larger CID detector also enables <strong>Intelligent Full Range, or iFR, mode</strong>, which captures the full elemental spectrum in one simultaneous acquisition. This reduces analysis time by eliminating sequential low- and high-wavelength exposures.</p><p>For applications requiring improved UV performance, <strong>enhanced UV, or eUV, mode</strong> provides added sensitivity for key elements with emission lines in the low UV range.</p><h3><strong>Key takeaways from the optical and detector design</strong></h3><p>The practical benefits of the iCAP PRO ICP-OES compact optical design combined with the unique and proprietary CID technology are clear:</p><ul><li>High sensitivity,</li><li>Faster analysis,</li><li>Reduced spectral interferences,</li><li>Better performance in high-matrix samples, and</li><li>Greater confidence in the analysis of complex sample matrices.</li></ul><p>The same rich, simultaneous spectral data captured by the CID detector also helps power advanced software capabilities such as the innovative <strong>AI-driven SemiQuant</strong>, giving analysts rapid insight into unknown samples without having to build a calibration curve.</p><h3><strong>AI-powered SemiQuant: instant sample insight</strong></h3><p>One of the most compelling parts of the on-demand webinar is the software demonstration, including a deep dive into the new <strong>AI-powered SemiQuant</strong> feature within the<a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1489"><strong> Thermo Scientific Qtegra Intelligent Scientific Data Solution (ISDS) software</strong></a>.</p><p>Traditional ICP-OES method development often starts with several questions: Which elements are present? What concentration ranges should be expected? Which wavelengths should be selected? What interferences might occur? Which samples need dilution?</p><p>AI-powered SemiQuant helps answer those questions faster. Using the rich, simultaneous spectral information captured by the CID detector, SemiQuant evaluates many wavelengths for each element rather than relying on a single emission line.

How to Simplify ICP-OES Analysis: Method Development, High Matrix Samples, and Daily Operation

<p><strong>In this leaflet we discuss whether or not you should correct for an observed significant bias and the impact this may have on the measurement uncertainty (MU). How to apply the correction and how to increase the uncertainty to take account of an uncorrected bias is outside the scope of this leaflet.&nbsp;</strong></p><p>Important issues for deciding on how to treat an observed significant bias are:&nbsp;</p><ul><li>whether we understand the cause of the bias, and&nbsp;</li><li>whether its size can be reliably determined.&nbsp;</li></ul><p><strong>Further we must decide:&nbsp;</strong></p><ul><li>whether the bias is consistent for all test samples within the scope of the method and&nbsp;</li><li>whether any correction for bias should be multiplicative or additive, depending on whether the magnitude of the bias is constant or changes with the concentration level.</li></ul><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Treatment_of_an_observed_bias_2_d221a32b8b.jpg" alt="Eurachem: Treatment of an observed bias" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Treatment_of_an_observed_bias_2_d221a32b8b.jpg 245w," sizes="100vw" width="1528" height="448"></p><h4><strong>Should we correct, and should we increase the measurement uncertainty?&nbsp;</strong></h4><p>The ISO Guide to the expression of uncertainty in measurement, GUM [1], assumes that “the result of a measurement has been corrected for all <strong>recognised significant</strong> systematic effects” (GUM 3.2.4). This implies that when developing a measurement method all known sources of bias should be investigated and if possible, eliminated or their effect minimised. If this cannot be achieved, then, if appropriate, a correction should be applied and the measurement uncertainty revised.&nbsp;</p><p>Let’s assume we have available a standardised method or a fully developed in-house method, with a clear description of the measurand, where any known bias has been minimised during method development (e.g. the effect of interferences has been minimised or a correction is included in the method). The next step, as a part of the validation, is to reliably determine any additional bias for the concentration interval and different matrices specified within the scope of the method. On the next page we present a roadmap outlining how to handle any additional significant bias.&nbsp;</p><p>Note that the observed bias in a laboratory could be due to laboratory as well as method bias. For empirical methods where the measurand is operationally defined by the method, the method bias is by definition zero, however, the laboratory bias still needs to be considered.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Treatment_of_an_observed_bias_3_5d99940abd.jpg" alt="Eurachem: Treatment of an observed bias" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Treatment_of_an_observed_bias_3_5d99940abd.jpg 62w," sizes="100vw" width="426" height="1060"></p><ol><li>There is no point in trying to eliminate or correct a small bias, since both elimination and correction need resources.&nbsp;</li><li>If bias is not negligible then the best approach, if possible, is to try to eliminate it by modifying the method.&nbsp;</li><li>If bias is not negligible, but eliminating it is either impossible or impractical, then we can consider correcting for bias. There are three possibilities:&nbsp;<ul><li>Correction may be required (e. g. by regulations).&nbsp;</li><li>Correction may be forbidden, in which case no correction should be made.&nbsp;</li><li>Correction may be allowed. Then we should look at two more criteria to determine whether correction is justified.&nbsp;</li></ul></li><li>If bias can be reliably determined and a correction method can be applied that is relevant for all test samples within the scope of the method we may decide to correct for bias. However, if the cause of bias is not known then correcting for bias cannot be generally recommended. If bias cannot be reliably determined then we should not correct for it. If we correct the result on the basis of an unreliable bias estimate then we may even increase the uncertainty of the results.&nbsp;</li><li>Correcting for bias is meaningful only if a useful reduction of measurement uncertainty (MU) is achieved. Correcting for the bias is only meaningful if the MU of the correction is smaller than the component of the MU arising from not applying the correction.&nbsp;</li></ol><p>If a significant bias is not corrected, it is difficult to give clear guidance on what action to take. For the case of recovery correction, IUPAC [2] lists some possibilities if no correction is applied:&nbsp;</p><ol><li>No action;&nbsp;</li><li>Report recovery separately, including the uncertainty of both the result and the recovery&nbsp;</li><li>Take the bias into account in the uncertainty estimate of the results</li></ol><p>These principles can be applied to other forms of bias. Further options have also been reviewed in the literature: See, for example, reference [3]</p>

Agilent Technologies: Determination of Toxic Elements in Durian and Jackfruit Using an Agilent Automated ICP-MS System According to China GB 5009.268</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_icpms_durian_5994_9351en_agilent_fcafe537c7.pdf"><strong>Full PDF for download</strong></a><strong>&nbsp;</strong></li></ul><p>Fruit is an essential part of daily human nutrition, providing vital vitamins, minerals, and dietary fiber.3 The Chinese market, with over 1.4 billion people, has become one of the largest fruit markets in the world. It is expected that China's total fruit consumption will reach about 312 million tons by 2025.4 Additionally, fruit imports are projected to exceed 9 million tons annually, underscoring the country's strong domestic demand and reliance on imported supplies.&nbsp;</p><p>Within this context, China has become a major export destination for Asian countries, including Vietnam, Thailand, Laos, Cambodia, Philippines, Indonesia, and others. Thanks to favorable climate conditions and a wide variety of tropical fruit cultivars, these countries have strategically increased their fruit exports to satisfy Chinese market demand. Specifically, products such as durian and jackfruit have gained significant popularity, playing an increasingly vital role in regional agricultural trade.&nbsp;</p><p>However, the biggest challenge for those countries when entering the Chinese market is strict food safety regulations, especially limits on trace elements and heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), and arsenic (As). The General Administration of Customs of the People's Republic of China (GACC) sets very low Maximum Residue Limits (MRLs, Table 1). Additionally, the large, continuous volume of fruit exports makes time a critical factor, as any delay can affect product quality and reduce its economic value. This situation places significant pressure on testing laboratories, requiring the development of stable, rapid, and accurate methods to ensure continuous and reliable operations.&nbsp;</p><p>To address these challenges, the Agilent ICP Workflow Automation System offers a practical solution. The ICP‑MS 7900 provides high-throughput, highly sensitive, and precise measurements of trace elements and heavy metals, including Pb, Cd, Hg, and As. The combination of ADS2 and AVS helps reduce sample turnaround time and cost per analysis. The Advanced Dilution System (ADS2) automatically performs important tasks such as preparing a multipoint calibration from a single stock standard up to 400 times, diluting samples above the calibration range, or, if there is an internal standard recovery issue, eliminating the need for manual dilution. The Advanced Valve System (AVS) automatically rinses the sample introduction system while the next sample is being analyzed, virtually eliminating the delays typical of conventional analysis. Using controlled argon bubble injection between the sample and rinse solution prevents mixing, reducing uptake and rinse times. This study describes the use of the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=7900"><strong>Agilent 7900 ICP-MS</strong></a>, <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=SPS+4"><strong>Agilent SPS 4 autosampler</strong></a>, <strong>AVS</strong>, and <strong>ADS2 auto-dilution</strong> for the analysis of four toxic elements in durian and jackfruit samples using the China GB 5009.268 method.<sup>1</sup></p><h4><strong>Results and discussion&nbsp;</strong></h4><h5><strong>Automatic calibration standards and Instrument stability&nbsp;</strong></h5><p>A 7-point calibration curve automatically prepared using the ADS 2 demonstrated excellent linearity over the concentration range of 0.05–10 µg/L. Using a 1/x weighted regression without forcing the calibration through the origin, all analytes achieved coefficients of determination (R²) ≥ 0.995 (Figure 3), with back-calculated concentrations within 90–110% of their theoretical values, confirming the suitability of the calibration range for routine quantification. The integrated automation workflow significantly improved laboratory productivity by completing calibration preparation and analysis in approximately 1.5 minutes per sample. By minimizing manual operations and operator intervention, the ADS 2 reduced the risk of contamination and human error while enabling higher sample throughput for routine food safety testing.&nbsp;</p><p>To evaluate instrument stability during continuous operation, the variation in internal standard recoveries was monitored throughout an analytical sequence of more than 70&nbsp;consecutive samples. The recoveries of the three internal standards across different measurement modes remained consistently within the ±20% acceptance limit throughout the analytical sequence (Figure 4). Blank samples interspersed between concentration intervals showed no evidence of carryover, demonstrating effective system cleanliness and analytical robustness. These results confirm the excellent long-term stability and robust matrix tolerance of the Agilent 7900 ICP-MS, providing reliable performance for high-throughput routine food safety testing.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>The Agilent 7900 ICP-MS, integrated with the SPS 4 autosampler, ADS 2, and AVS, delivers a fully automated, high-throughput workflow for routine trace-level multi-element analysis. By eliminating manual standard preparation and minimizing operator intervention, the solution reduces labor costs, improves data consistency, and empowers laboratories to maximize productivity and analytical capacity to meet increasing testing demands.&nbsp;</p><p>Excellent sensitivity, long-term stability, and robust interference removal, together with satisfactory recoveries, repeatability, and reproducibility for As, Cd, Pb, and Hg at an LOQ of 5 µg/kg, demonstrate reliable analytical performance. Compliance with Chinese regulatory requirements further position the Agilent automation solution as a cost-effective platform for high-volume food safety testing and export quality assurance, enabling laboratories to confidently support the growing demand for exports to the Chinese&nbsp;market.</p><h3><strong>2. Shimadzu: TOC Evaluation of Surfactants</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01160_en_539fba0ba2.pdf"><strong>Full PDF for download</strong></a></li></ul><h5><strong>User benefits</strong></h5><ul><li>TOC can be evaluated accurately using the TC-IC method, even for foaming surfactants.&nbsp;</li><li>The ASI-L autosampler enables automatic, continuous measurement of multiple samples, improving analytical efficiency.</li></ul><p>Surfactants are important chemicals widely used in detergents and dispersants for pharmaceutical equipment cleaning processes, chemical manufacturing processes, and environmental water management. If surfactant residues remain after such processes, they can not only affect manufacturing processes and final product quality, but also increase the organic load in wastewater and environmental water. Therefore, quality control is also needed for organic matter derived from surfactants.&nbsp;</p><p>Total organic carbon (TOC) analysis is effective for evaluating the quality of surfactants. In general, the NPOC (non-purgeable organic carbon) method is often selected for TOC measurement in terms of sample volume and analysis time requirements. On the other hand, because surfactants have both hydrophilic and hydrophobic groups in their structure, they tend to foam even at low concentrations. When such samples are measured by the NPOC method, which involves acid addition and sparging, foaming can cause the sample to overflow from the syringe vessel inside the instrument into the waste line. That can result in measurement valuesthat are lower than the true value.&nbsp;</p><p>This article compares TOC measurement results for surfactants obtained by the NPOC method and the TC-IC method using the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=TOC-L"><strong>Shimadzu TOC-L total organic carbon analyzer</strong></a>, which uses the combustion oxidation method.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>Table 5 summarizes the results obtained by measuring sodium dodecylbenzenesulfonate solutions, used here as representative surfactant samples, by the NPOC method and the TC-IC method. With the NPOC method, the TOC recovery rates were below 50 % for all samples, whereas the TC-IC method produced satisfactory TOC recovery rates close to 100 % for all samples.</p><p>Sodium dodecylbenzenesulfonate solutions (carbon concentration: 0.5 mg/L) is also used in Japanese Pharmacopoeia (JP) recovery tests. For surfactants that readily foam, such as in this example, NPOC measurements involving acid addition and sparging may affect measurement accuracy due to sample loss. For such samples, accurate TOC values can be obtained by using the TC-IC method. In addition, by using the ASI-L autosampler, multiple samples can be measured automatically and continuously.</p><h3><strong>3.

LECO RC612 Multiphase Determination of Carbon and Water

The LECO RC612 delivers fast carbon and water determination with advanced carbon form differentiation, flexible furnace programming, IR detection, and optional automation in a compact, easy-to-use system.

<p><strong>The RC612 is a state-of-the-art analyzer designed for fast and reliable determination of carbon and water in a wide range of organic and inorganic materials. In addition to total carbon and moisture quantification, the RC612 enables differentiation between multiple carbon forms, providing deeper insight into sample composition. Its compact footprint, robust construction, and intuitive operating software make it a powerful yet easy-to-use solution for routine and advanced laboratory applications.</strong></p><h4><strong>Key Features</strong></h4><ul><li>Complies with <strong>AWS (ANSI) approved methods</strong> for determination of moisture content in welding fluxes and welding electrode flux coverings</li><li>Supports both <strong>qualitative and quantitative analysis</strong></li><li><strong>Easy-to-install combustion tube</strong> simplifies maintenance and reduces downtime</li><li>Large-diameter reaction tube enables moisture analysis of diverse sample types, including powders, flat strips, and tubular sections</li><li>Differentiation of <strong>surface, free, organic, and inorganic carbon</strong> forms</li><li>Optional <strong>rugged 50-position autoloader</strong> for unattended, automated operation</li><li>Built-in <strong>on-board diagnostics</strong> to minimize downtime and support reliable performance</li></ul><h4><strong>Theory of Operation</strong></h4><p>The RC612 multiphase carbon and hydrogen/moisture determinator measures carbon and water content in organic and inorganic samples while distinguishing between different carbon sources. The system employs a dual-stage furnace with advanced temperature control, programmable from near ambient up to 1100 °C, allowing tailored thermal programs for specific applications.</p><p>During analysis, the operator can define multiple furnace steps and select either oxygen or nitrogen as the purge gas to create oxidizing or inert conditions. Under these controlled environments, carbon- and water-containing components are either combusted or reacted. An integrated afterburner furnace, typically operated at 850 °C, together with a secondary oxidation catalyst, ensures complete conversion of all evolved components.</p><p>Quantification is performed using <strong>infrared (IR) detection</strong>, with results reported as weight percent or coating weight (mg/in²). When samples are combusted in an oxidizing atmosphere, nearly all carbon forms are converted to CO₂. Organic carbon is identified by the simultaneous formation of CO₂ and H₂O, producing coincident IR signals. In inert conditions, water and carbonates are detected while organic carbon is generally not observed, enabling selective differentiation of carbon species.</p><p>For unknown samples, a slow temperature ramp program (for example, 100 °C to 1000 °C at 20 °C/min) can be applied. This approach reveals the temperatures at which various carbon forms oxidize or volatilize, allowing optimization of furnace programs for faster and more targeted quantitative analysis in routine workflows.</p>

The system supports two analytical approaches: residual (total) hydrogen determination and combined diffusible plus residual hydrogen determination when equipped with the optional piercer.</p><p>For <strong>residual (total) hydrogen analysis</strong>, a pre-weighed sample is placed directly into the furnace. Hydrogen is released from the sample by hot extraction and carried into a flowing inert gas stream. The evolved hydrogen is quantified using a thermal conductivity detector, and results are reported in parts per million (ppm). Samples are typically collected using LECO vacuum pin tubes or equivalent techniques.</p><p>For <strong>diffusible and residual hydrogen analysis</strong>, a sampler is first placed into the optional piercing unit. The sampler is punctured, allowing diffusible molecular hydrogen to be purged into the carrier gas stream and measured by the thermal conductivity detector. After diffusible hydrogen measurement, the sampler is removed, the outer shroud is taken off, and the remaining pin sample is weighed. This sample is then introduced into the furnace, where residual hydrogen is released by hot extraction and quantified. Final hydrogen concentrations are reported in ppm, providing a complete hydrogen profile from a single instrument.</p><h4><strong>Available Models</strong></h4><ul><li><strong>DH603DC</strong> – DH603 with diffusible hydrogen piercer</li><li><strong>DH603C</strong> – DH603 for residual (total) hydrogen determination</li></ul>
