🎤 Presenter: Barbara Grace Saunders (William &amp; Mary, Williamsburg, USA)💾 <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/paper/32782">PDF presentation</a><h3>Abstract</h3>Gunshot residue (GSR) is expelled as a "plume" of vaporized material during a firearm discharge event. As it disperses, condenses, and settles on surfaces in vicinity of the discharge, it creates chemical depositions that provide essential information for forensic casework involving criminal firearm usage.GSR contains organic (OGSR) and inorganic (IGSR) components, both of which may carry evidentiary value. Traditional analyses involve the targeted point analysis of IGSR via scanning electron microscopy - energy dispersive x-ray spectroscopy (<a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?search=SEM-EDS">SEM-EDS</a>), and conclusions are drawn based on a well-established elemental and morphological profile "characteristic" to IGSR. This method has lost impact as a standard for forensic analysis due to increased use of "green" - heavy metal-free - ammunition, which omits the lead, barium, and antimony that are traditionally seen as the "characteristic" markers of GSR.This study aimed to develop a holistic approach to the analysis of GSR using both SEM-EDS as a targeted approach to IGSR analysis and comprehensive two-dimensional gas chromatography – time-of-flight mass spectrometry (<a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?instrumentationItems=2-3-13">GC×GC-TOFMS</a>) as a nontargeted approach to OGSR analysis. GSR samples were collected from the hands of shooters at a police firearms recertification training using the tape lift method. SEM-EDS was used to identify IGSR and develop new morphological and elemental profiles for heavy metal-free residues. OGSR components have been positively identified through sample analysis via liquid extraction, chromatographic separation via GC×GC-TOFMS, and data processing.Future work on this project will include the optimization of data processing methods and the development of SPME as an alternative sample extraction method.<h3>Video Transcription</h3>The transition toward environmentally friendly “green” ammunition is creating new challenges for forensic laboratories. Traditional gunshot residue (GSR) analysis relies heavily on the detection of heavy-metal-containing particles produced during firearm discharge. However, modern ammunition formulations increasingly eliminate these metals, making conventional forensic protocols less effective.This study presents the development of a combined analytical strategy for the characterization of green gunshot residue (GSR) by integrating:<ul><li>Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS) for inorganic GSR (IGSR)</li><li>Comprehensive Two-Dimensional Gas Chromatography coupled to Time-of-Flight Mass Spectrometry (GC×GC-TOFMS) for organic GSR (OGSR)</li></ul>The ultimate goal is to provide forensic laboratories with a more complete and defensible analytical approach for firearm discharge investigations.<h4>Why Green Gunshot Residue Is a Challenge</h4>Gunshot residue consists of particulate matter expelled from firearms during discharge. Rapid increases in temperature and pressure vaporize materials originating from:<ul><li>primer compositions</li><li>bullets</li><li>cartridge cases</li><li>firearm components</li></ul>These materials rapidly condense and deposit on:<ul><li>hands</li><li>skin</li><li>hair</li><li>clothing</li><li>nearby surfaces</li></ul>Because GSR is directly associated with firearm discharge events, it remains an important source of forensic evidence.Historically, forensic scientists have identified GSR using SEM-EDS, focusing on particles containing characteristic heavy metals.However, ammunition manufacturers have increasingly removed heavy metals from primers due to health and environmental concerns. Modern green ammunition replaces traditional metallic components with more environmentally common elements, making classical identification criteria less reliable.<h4>Project Objectives</h4>The project was designed around three primary goals:<ol><li>Redevelop inorganic GSR classification criteria for green ammunition.</li><li>Develop a robust GC×GC-TOFMS workflow for organic GSR analysis.</li><li>Combine both approaches into a comprehensive forensic methodology suitable for future laboratory implementation.</li></ol><h4>Collection of Green GSR Samples</h4>Samples were collected using standard forensic SEM-compatible collection kits.Each kit consisted of:<ul><li>an airtight glass vial</li><li>an aluminum SEM pin stub</li><li>black carbon adhesive for particle collection</li></ul>Sampling was performed by repeatedly dabbing the adhesive surface across:<ul><li>palms</li><li>backs of hands</li><li>forearms</li></ul>of volunteers.To ensure authentic green GSR samples, collection took place during police firearms recertification training at a local firing range. All ammunition used was verified as green ammunition.<h4>Redevelopment of Green IGSR Characterization by SEM-EDS</h4>The first phase focused on updating SEM-EDS criteria for green ammunition residues.Analysis of numerous samples revealed morphological and elemental characteristics that differed from traditional heavy-metal-containing GSR particles.One notable observation was that many candidate particles exhibited a characteristic “sparkling” appearance against the SEM background. These particles often contained elevated metallic content, although not necessarily heavy metals.The resulting profiles provided a more reliable framework for identifying inorganic components of green GSR.Nevertheless, the approach still involved a degree of analyst judgment, motivating the development of a more objective complementary analytical strategy based on organic residue analysis.<h4>Why GC×GC-TOFMS Was Selected</h4>The second phase focused on characterization of organic gunshot residue (OGSR).Compared with conventional one-dimensional GC, GC×GC offers:<ul><li>increased chromatographic peak capacity</li><li>enhanced separation power</li><li>improved resolution of structurally similar compounds</li><li>better discrimination of constitutional isomers</li></ul>These advantages are particularly valuable for forensic samples, where highly complex mixtures often contain numerous nitroaromatic compounds and energetic materials.The instrumentation used was a:<ul><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/37">LECO Pegasus BT GC×GC-TOFMS</a></li></ul>which combines comprehensive two-dimensional gas chromatography with high-resolution time-of-flight mass spectrometric detection.<h4>Development of the Organic GSR Extraction Method</h4>Organic residues were extracted using a liquid extraction procedure adapted from OSAC recommendations for GC-MS analysis.The workflow included:<ol><li>Extraction in methanol</li><li>Evaporation to dryness under nitrogen</li><li>Reconstitution</li><li>Transfer into GC×GC-compatible vials</li></ol>Additional vortexing and sonication steps were incorporated to maximize analyte recovery.<h4>Comparison of Extraction Procedures</h4>The newly developed in-house method was compared with a literature-based extraction protocol.The results demonstrated that the in-house procedure:<ul><li>recovered more analytes</li><li>produced higher peak intensities</li><li>generated a larger average number of chromatographic peaks</li></ul>Important target compounds such as:<ul><li>diphenylamine</li><li>skin matrix compounds</li><li>nitroaromatic species</li></ul>were detected at significantly higher abundance levels.Consequently, the in-house extraction method was selected for all subsequent experiments.<h4>Optimization of the GC×GC Method</h4><h5>Carrier Gas Selection</h5>Initial experiments compared helium and hydrogen carrier gases.Hydrogen provided:<ul><li>improved chromatographic expansion</li><li>better compound visibility</li><li>enhanced separation</li></ul>Therefore, hydrogen was selected for the final method.<h5>Inlet Temperature Optimization</h5>Two inlet temperatures were evaluated:<ul><li>170 °C</li><li>200 °C</li></ul>Although the lower temperature generated a larger number of detected analytes overall, critical GSR target compounds such as:<ul><li>nitroglycerin (ethylene glycol dinitrate)</li><li>diphenylamine</li></ul>showed lower responses or were not detected.As a result, 200 °C was selected as the optimal inlet temperature.<h5>Modulation Period Optimization</h5>Three modulation periods were compared: 2.0 s / 2.5 s / 3.0 s<ul><li>Two-Second Modulation: Produced wraparound effects where analytes could not fully elute within a modulation cycle.</li><li>Three-Second Modulation: Created excessive unused chromatographic space and compressed analyte distributions.</li><li>Two-and-a-Half-Second Modulation: Provided the best balance between resolution and chromatographic efficiency.</li></ul>Therefore, 2.5 seconds was selected as the final modulation period.<h4>Validation Using Analytical Standards</h4>The optimized GC×GC method was validated using several reference standards.<h5>Seven-Component Phthalate Standard</h5>All seven analytes were successfully identified.The compounds exhibited:<ul><li>excellent chromatographic resolution</li><li>reproducible retention behavior</li><li>clear separation across both chromatographic dimensions</li></ul>These retention regions subsequently helped identify corresponding compounds in authentic GSR samples.<h5>Twelve-Component Nitroaromatic Standard</h5>All twelve analytes were successfully identified.Particularly important was the clear separation of compounds such as:<ul><li>TNT</li><li>DNT</li><li>nitrotoluenes</li></ul>which frequently appear in explosive and propellant formulations.This experiment demonstrated the superior resolving power of GC×GC compared with conventional one-dimensional GC.<h5>Nitroglycerin Standard</h5>Nitroglycerin was successfully detected and its retention coordinates established.These retention characteristics will serve as reference markers for future identification in authentic GSR samples.<h5>Gun Surveillance Standard</h5>The final validation mixture contained nine known compounds.Seven components were successfully identified.Two unexpected compounds:<ul><li>phenazine</li><li>benzothiazole</li></ul>appeared in the chromatograms, while one expected analyte overlapped with column bleed.Although further refinement is required, the preliminary results demonstrated promising analytical performance.<h4>Major Outcomes of the Study</h4>The project has already produced several significant achievements:<h5>Inorganic GSR Analysis</h5><ul><li>Redesigned SEM-EDS classification profiles for green ammunition residues</li><li>Improved characterization of heavy-metal-free particles</li></ul><h5>Organic GSR Analysis</h5><ul><li>Optimized methanol-based extraction procedure</li><li>Fully developed GC×GC-TOFMS analytical workflow</li><li>Improved detection of key OGSR markers</li><li>Verified retention behavior of multiple relevant analytes</li></ul><h5>Integrated Forensic Strategy</h5><ul><li>Combined IGSR and OGSR characterization</li><li>Enhanced confidence in green GSR identification</li><li>Improved potential for courtroom-defensible evidence interpretation</li></ul><h4>Future Work</h4>Although the method successfully distinguishes the presence or absence of green GSR, additional validation remains necessary before routine forensic implementation.Future investigations will focus on:<ul><li>comparison of sorbent-based extraction approaches with methanol extraction</li><li>acquisition of retention indices for stronger compound confirmation</li><li>further validation of target analyte identities</li><li>increased method robustness for forensic casework</li></ul>The ultimate objective is to establish a validated methodology suitable for routine forensic laboratory deployment in the era of green ammunition.<h4>Conclusion</h4>This study demonstrates that combining SEM-EDS and GC×GC-TOFMS provides a promising framework for the forensic analysis of modern green gunshot residue. By integrating inorganic and organic residue characterization, forensic scientists can generate a more comprehensive evidential profile of firearm discharge events. The optimized extraction protocol, chromatographic conditions, and preliminary validation results show strong potential for future implementation in forensic laboratories, helping maintain the evidential value of GSR as ammunition technologies continue to evolve.<blockquote>This text has been automatically transcribed from a video presentation using AI technology.

Agilent Technologies: Analysis of Soil and Sediments by ICP-MS with Advanced Sample Introduction Tools</h3>Simplified sample preparation enabled by the Agilent Mira Mist Nebulizer and an In-Line Particle Filter<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_enviro_soil_sample_prep_9500_icp_qqq_5994_9126en_agilent_8299f007e9.pdf">Full PDF for download</a></li></ul>ICP-MS is widely employed for monitoring inorganic elements in soil and sediments, with established methods such as US EPA 6020B providing a validated framework for the accurate, multi‑element analysis of environmental samples.1 In a separate study, we demonstrated the outstanding performance capabilities of the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500">Agilent 9500 Triple Quadrupole ICP-MS</a> (ICP-QQQ) in compliance with EPA 6020B requirements.2 The instrument, which includes the Ultra High Matrix Introduction (UHMI) system for enhanced plasma stability and robustness, employed Advanced Helium Mode (AHM) and Air cell mode to achieve lower limits of detection (LODs) compared to conventional cell gas approaches.3,4The two collision/reaction cell (CRC) modes of operation were enabled by the Agilent Dual-Cell System (DCS) —a unique CRC that provides the following performance advantages when operated in AHM and Air cell mode: – AHM – This innovative He-based gas collision-cell mode significantly enhances sensitivity for low-mass analytes while providing robust interference removal across the entire mass range. – This single gas mode eliminates the need for multiple modes, replacing no gas, conventional He, and high energy (HE) He mode. – Air cell mode – Using oxygen (O2 ) from air and an integrated air filter for the 9500 ICP-QQQ, Air cell mode leverages reactions between O2 and analytes to improve detection limits (DLs) for oxygen-reactive species. – Air cell mode effectively eliminates interferences, including M++ that are challenging to resolve using He-based gas methods.5 – With an unlimited supply of O2 in air, Air cell mode eliminates the need for O2 gas cylinders, reducing operating costs and simplifying workflows.Of all the ICP-MS nebulizers, the Agilent Mira Mist nebulizer offers the best resistance to concentrated acids and organic solvents. Its parallel path design ensures good tolerance to high levels of particulates and total dissolved solids (TDS), providing excellent resistance to clogging. In this study, the 9500 ICP-QQQ equipped with an in-line particle filter and Mira Mist nebulizer was used to determine trace and major elements in five environmental certified reference materials (CRMs) and a real sediment sample. The performance of the method was evaluated according to criteria set out in EPA Method 6020B.<h4>Experimental&nbsp;</h4><h5>Instrumentation&nbsp;</h5>All measurements were performed using an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500">Agilent 9500 ICP-QQQ</a> that includes the following standard components: nickel (Ni) interface cones and newly designed DCS cell. The design features and functionality of the 9500 and DCS are explained elsewhere.3,4 The 9500 was also equipped with the optional Agilent Advanced Valve System (AVS&nbsp;MS) discrete sampling system for improved productivity. The AVS&nbsp;MS system’s high-speed piston pump works seamlessly with the Agilent SPS 4 and SPS&nbsp;6 autosamplers for sample delivery, ensuring the high sample throughput necessary to meet the operational needs of most environmental testing laboratories.To optimize signal stability with the Mira Mist nebulizer, the nebulizer pump speed was adjusted and a makeup gas was introduced (Table 1). In the 9500 ICP-QQQ, both the makeup gas and dilution gas can be added, enabling finer control of the plasma gas flow rates to optimize signal %RSD within the target sensitivity zone. The lens parameters were set automatically using the Autotune function in the software. The in-line filter’s internal volume is sufficiently small that its presence does not influence AVS MS sample introduction timing or method parameters. As a result, the same settings were used with and without the filter installed (Table 2).<h4>Conclusion&nbsp;</h4>In this study, sediment samples were analyzed in accordance with EPA Method 6020B using the Agilent 9500 ICP‑QQQ with UHMI and the optional AVS MS. The system was equipped with advanced sample introduction components, including the Mira Mist nebulizer and an in‑line particle filter.&nbsp;The combination of the Mira Mist nebulizer and in-line filter enabled the analysis of sediment digests without a dedicated filtration step, reducing sample preparation time and consumable costs. At the same time, the configuration minimized the risk of sample introduction blockages, supporting robust and reliable long-term ICP-QQQ operation for complex environmental matrices.Overall, the 9500 ICP-QQQ with the Mira Mist nebulizer and the in-line particle filter achieved excellent analytical data:&nbsp;<ul><li>Low detection limits in the low ng/L (ppt) range for most analytes&nbsp;</li><li>The same or similar washout efficiency of sticky elements as a standard sample introduction configuration&nbsp;</li><li>The same sample introduction timing, regardless of whether the filter was installed or not&nbsp;</li><li>Method robustness and reproducibility over more than eight hours of continuous measurements, as demonstrated by the recoveries of ISTDs and CCVs within the limits specified in EPA Method 6020B&nbsp;</li><li>Recoveries of all certified elements in the five environmental CRMs, matrix spike sample, and spiked real sediment sample within ±10%, confirming the effective control of interferences using AHM and Air cell mode&nbsp;</li></ul>The study has highlighted how the 9500 ICP-QQQ with the Mira Mist nebulizer and in‑line particle filter enhances sample preparation efficiency and analytical performance for the analysis of complex sediment digests.<h3>2. Shimadzu: Analysis of Inorganic Elements in Urine Using EDXRF</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01007_en_c3bd71bbb3.pdf">Full PDF for download</a></li></ul><h4>User Benefits</h4><ul><li>Inorganic elements in urine can be quantified at the ppm level without any complicated sample pretreatment.</li><li>Qual-quantitative analysis is possible using the FP (Fundamental Parameter) method, which does not require standards.</li><li>Qual-quantitative results are obtained within 10 minutes per sample.</li></ul>Inorganic element poisoning, including heavy metals, is caused by accidents or criminal incidents, and the causative elements are diverse. Although some of these elements are highly toxic, there are cases in which it is difficult to distinguish them at an early stage because they lack specific symptoms of poisoning. Therefore, analytical methods for rapid screening of these elements are required in forensic research.&nbsp;Inorganic elements are generally analyzed by ICP-AES or ICP-MS. Although these techniques allow trace-level quantitation, they require chemical pretreatment such as dilution and deproteinization, and the samples are limited to liquid specimens. In contrast, energy dispersive X-ray fluorescence spectrometer (EDXRF - <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=EDX-7200">EDX-7200</a>) offers sufficient sensitivity in the concentration range associated with poisoning and enables simple, non-destructive analysis in a short time.&nbsp;This application describesthe results of quantitative analysis of 15 elements in urine by the calibration curve method, and qualquantitative analysis by the FP (Fundamental Parameter) method based on sensitivity coefficients installed in the instrument. The errors in the quantitative values obtained by the FP-based qualquantitative analysis method were approximately ±20 %, indicating that sufficient quantitative accuracy was achieved. Screening can be performed within 10 minutes persample.<h4>Conclusion</h4>The FP method demonstrated high accuracy for quantitation without calibration curves. Furthermore, urine samples do not require complicated pretreatment such as protein removal, and the analysis time is as short as approximately 10 minutes per sample. This method is well suited for poisoning screening in forensic research.<h3>3. Thermo Fisher Scientific: Analysis of copper alloys with the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1978">ARL X900 XRF Spectrometer</a></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/analysis_of_copper_alloys_arl_9900_an41427_203b52e126.pdf">Full PDF for download</a></li></ul><h4>Copper alloys&nbsp;</h4>are very important products because they are used for many applications and many manufacturing processes as described in the next few paragraphs. It is important to accurately analyze these materials to confirm compliance of their chemical specifications that imply physical properties, like conductivity, compressive strength, hardness, resistance to traction and to abrasion. High product quality and efficient production can be ensured with accurate analysis results. Copper alloys Pure copper is mixed with other elements to produce a wide range of alloys: Brasses (Cu-Zn), bronzes (Cu-Sn), gun metal (Cu-Sn-Zn) used for casting due to its excellent fluidity, for valves, taps and water fittings. Manganese bronzes (Cu-Zn-Mn) are not true bronzes as Sn is not the essential constituent. Used for rudders, propellers, and ship fittings. Cupro-nickel (Cu-Ni) used for coins, tubes, wires, electrical resistances, and thermocouples. Nickel silver (Cu-Ni-Zn) used for marine applications, car radiators and fittings.&nbsp;<h4>Brass&nbsp;</h4>One of the most important non-ferrous engineering alloys. It covers a large range of physical properties with multiple applications. Copper can hold about 39% of zinc in solid solution. Alloys containing less than 39% Zn are known as α-brasses. This brass (70/30) is very widely employed for cartridge, cases, condenser tubes, etc. From 39% to 46% of Zn, a β-solid solution gives αβ-brass. This alloy (60/40) is found in extensive engineering applications with enhanced corrosion resistance used in marine applications. Alloys containing more than 49% Zn are very hard and only used for brazing brasses.<h4>Instrument parameters and conditions&nbsp;</h4>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1978">ARL X900 XRF Spectrometer</a> can accommodate up to 24 fixed monochromator channels alongside the goniometer or up to 32 fixed monochromator channels when no goniometer is fitted. New high counting fixed channel monochromators using an SCX detector are available to further improve the precision of analysis, especially for elements like Cu, Zn and Ni.Our unique proprietary Moiré fringe goniometer ensures speed, flexibility and reliability of analysis thanks to the clever frictionfree positioning system. Up to nine crystals and four collimators can be fitted. With the two detectors (flow proportional and scintillation counters), precise elemental analysis from Boron to Californium is possible.&nbsp;The ARL X900 XRF spectrometer can be calibrated using commercially available certified reference materials (CRM) or well analyzed samples from the user. Calibrations can be delivered from the factory, hence reducing the commissioning time at the customer’s site.&nbsp;It should be stressed that an XRF spectrometer is a very accurate comparator, but the accuracy of the final analysis is entirely dependent on the quality of the standards used for calibration and on the care and reproducibility of sample preparation which must be identical for CRMs and for routine samples as well.This application note only includes data obtained mostly on fixed channels and on some goniometer channels. For more results using goniometer channels please refer to AN41426.<h4>Conclusion&nbsp;</h4>Analysis of all sorts of copper alloys can be performed with ease using the ARL X900 Simultaneous-Sequential XRF Spectrometer. The performance of the Moiré fringe goniometer is such that it can be used for analysis of any elements that are not fitted as fixed channels. The analysis on the goniometer is done while the fixed channels are measuring. In addition, it can be used as a backup in case of failure of any of the fixed channels.&nbsp;Appropriate calibrations for copper alloys can be delivered turnkey from the Thermo Fisher Scientific factory. In this case the commissioning time of the spectrometer is reduced to a minimum.&nbsp;The precision is excellent in these matrix types for routine or R&amp;D analysis, especially when the new high counting fixed channel monochromator is used for elements like Cu, Zn, and Ni.&nbsp;Furthermore, operation is made easy through the innovative <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2029">Thermo Scientific™ OXSAS™ Software</a> that operates with the latest Microsoft Windows® package.&nbsp;Thermo Fisher Scientific’s long experience in metals analysis comes from an installed base of over 2,000 XRF spectrometers worldwide. The ARL X900 spectrometer is the answer to your metallurgical analysis needs, whether they involve incoming material control, metal QC, or production analysis. Working 24 hours a day and 7 days a week, the ARL X900 spectrometer delivers dependable performance year after year. The high performance of the ARL X900 XRF Spectrometer will meet your analytical needs today and in the future

XRF in the Petrochemical Industry

<div><h5>What to expect?</h5>Porcelain — a fine, translucent ceramic originated in China, likely in Zhejiang province during the Eastern Han dynasty. It is made by firing kaolin at high temperatures (1260–1300 °C), giving it strength and beauty. Chinese porcelain, especially blue-and-white ware, became highly valued across Asia and the Islamic world. The cobalt blue pigment, rare and hard to source, was initially imported from Persia, linking Chinese porcelain to Middle Eastern trade. Before China’s mastery, early glazed pottery—often called “proto-porcelain”—appeared in the Islamic world. Arab artisans, known for their blue decorative styles, influenced later Chinese porcelain aesthetics. Porcelain carried cultural and economic importance: it was a luxury in Europe, a diplomatic gift in China, and a trade item in the Middle East. Its global spread reflects centuries of technological and artistic exchange. Studying porcelain offers insight into historical innovation and cross-cultural influence. Micro-X-ray fluorescence spectroscopy (micro-XRF) is a non-destructive method that can be used to study porcelain, offering both qualitative and quantitative capabilities.

These factors will be discussed during the presentation. In provenance studies, trace elements such as Rb, Sr, Y, and Zr serve as stable geochemical markers. Their resistance to surface alterations makes them valuable for comparing archaeological samples with reference materials, aiding in the identification of raw material sources and manufacturing regions. The pros and cons of different approaches required for optimal quantification will also be presented, illustrating the potential for accurate analysis under ideal measurement conditions. The ability of micro-XRF to detect elements beneath glaze layers is especially important for pigment identification, offering deeper insight into an object's history.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Bruker_Fig_2_Micro_XRF_scan_elemental_distribution_offers_to_identify_colourants_as_in_this_20th_century_hard_paste_porcelain_colour_palette_from_the_Sevres_Manufacture_et_Musee_Nationaux_8e2bd0d758.jpg" alt="Bruker: Fig. 2 Micro-XRF scan elemental distribution offers to identify colourants, as in this 20th century hard paste porcelain colour palette from the Sèvres Manufacture et Musée Nationaux." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Bruker_Fig_2_Micro_XRF_scan_elemental_distribution_offers_to_identify_colourants_as_in_this_20th_century_hard_paste_porcelain_colour_palette_from_the_Sevres_Manufacture_et_Musee_Nationaux_8e2bd0d758.jpg 154w," sizes="100vw" width="419" height="424">In summary, micro-XRF provides non-invasive, detailed chemical analysis of porcelain, supporting both scientific and cultural heritage research through layer analysis, provenance tracing, and pigment identification.
