1. Agilent Technologies: Critical Factors Affecting Cost-of-Ownership of ICP-MS
- Technical note
ICP-MS in high-throughput commercial laboratories
ICP-MS is the technique of choice for metals laboratories, due to its unique combination of full coverage for all regulated analytes including mercury,
low detection limits, and high sample throughput. But not all ICP-MS systems are equally suited to the needs of commercial laboratories.
Agilent’s 7850 and 7900 ICP-MS systems provide a powerful, integrated solution for the most demanding applications. Software tools, auto-optimization, and method/report templates streamline setup and routine operation, while high matrix tolerance, simple, reliable helium cell gas mode, and wide dynamic range simplify routine analysis of varied sample types.
In this Technical Overview, we show how productivity gains and long-lifetime consumables contribute to making Agilent ICP-MS instruments the ideal choice for high-throughput commercial laboratories.
System Suitability
The Agilent 7900 single quadrupole ICP-MS is optimized to deliver the high levels of performance needed for more difficult applications. As a result, the detector settings and thresholds are set to achieve the high sensitivity typically required in these demanding applications. Even so, for a typical suite of around 40 analytes and internal standard (ISTD) elements, the EM lifetime calculations indicate that a laboratory running 300 drinking water samples per day and operating 20 days per month can expect their Agilent 7900 ICP-MS EM detector will typically last more than 10 years. Even laboratories running high matrix samples with analyte levels between 100 ug/L (ppb) and 10 mg/L (ppm) can expect almost 6 years of operation from their Agilent 7900 ICP-MS detector.
The Agilent 7850 single quadrupole ICP-MS is optimized for more routine applications, where factors such as stability, sample throughput and low operating costs are typically more important than achieving the highest sensitivity. Consequently, the detector settings and thresholds of the 7850 detector are optimized for extended life with lower sensitivity than on the 7900. This means that the lifetime of the EM detector used in the Agilent 7850 ICP-MS is typically around twice as long as the figures quoted above for the EM detector used in the 7900.
As well as the lower cost of replacement detectors, this long lifetime also contributes to reduced maintenance downtime, further enhancing productivity.
2. Thermo Fisher Scientific: WPC: High throughput and robust analysis of fertilizers using ICP-OES
- Poster / WPC
ABSTRACT
Analytical testing laboratories frequently deal with heavy sample loads and a large suite of analytes but have limited time for delivering accurate results. In order to accomplish the desired productivity, short sample run times, robust methods, and minimum instrument downtime are fundamental requirements in such laboratories. This can be achieved with a technology such as inductively coupled plasma optical emission spectroscopy (ICP-OES) because it is traditionally highly matrix tolerant and modern ICP-OES instruments can additionally offer high sensitivity and speed.
INTRODUCTION
The developed method measures major and trace elements in the radial mode that covers the full spectrum in a single exposure, from UV to visible range,
simultaneously for all selected wavelengths without any additional data acquisition time. The small exposure times, when coupled with the Step Ahead feature of the autosampler, help realize a run time of only 36 s per sample (inlcuding uptake, analysis, and rinse) without the use of a discrete sampling valve. The method has been validated using standard reference materials, spike tests and a >5 hours long robustness test including >500 samples and regular QC checks. The results demonstrate high robustness and reliability, making the method an ideal choice for many different sectors where high productivity is required for anaylsing samples like water, waste water, soil, fertilizer, animal feed quality control, battery components and more.
CONCLUSIONS
- A quick and simple method with a run time of 36 s per sample (including uptake and wash) for a full analysis of elements present in fertilizers has been developed
- The use of the Step Ahead feature available on the iSC-65 autosampler compliments the speed of the iCAP PRO XP ICP-OES DUO. The combination of both provides the opportunity to reduce sample turnover times further by almost 30%.
- The method allows to achieve the typically required limits of quantifications for commonly regulated elemental contaminants in fertilizers and at the same time it can cover a large linear dynamic range between 0.01 – 20 mg·kg-1 for trace elements and 1 – 1500 mg·kg-1 for elements present in higher concentrations.
- The concept of the application can be easily extended to other sample types, such as soil or wastewater analysis. ICP-MS instruments can also benefit from single mode measurement and the high-speed capabilities of the iSC-65 autosampler.
3. Bruker: Oil in Water Analysis by Solid Phase Extraction
- Application
About oil, grease and water pollution
Many international legislations acknowledge that the monitoring of oil and grease content of industrially used (waste) water is essential to protect aquatic and human life.
The 1974 US Clean Water Act mentions oil and grease as a conventional pollutant. This term describes a water pollutant that is amenable to treatment by a municipal sewage treatment plant.
Wherever oil and grease are handled industrially and on a larger scale (e.g. offshore oil-rigs) their discharge into the environment should be tested.
Analysis of oil and grease in water
The current standard methods use highly flammable solvents such as pentane or hexane, to extract oil and grease from water. The extract is then analyzed by gas-chromatography (GC), or evaporated to measure the residue.
Since pentane and hexane are highly flammable and form explosive gas-air mixtures, the use of these solvents on oil platforms is not permitted. Hence, the wastewater samples are transferred to a mainland lab, which is a very costly and time consuming procedure.
FT-IR as ASTM approved alternative
The ASTM approved ”Standard test method for solvent-free membrane recoverable oil and grease by Infrared determination D7575” is a more convenient alternative. Briefly, this method quantifies oil and grease by processing a water sample through an oil capturing membrane and analyzing the membrane by transmission infrared spectroscopy. The membrane material does not block in the infrared range of interest.
Since this method does not use flammable and hazardous solvents, it can be performed on-site without moving the sample to the main analytical facility. This considerably reduces time for the analysis and enables near-real-time feedback and control for customers.
Conclusions and summary
Bruker‘s ALPHA II FT-IR in combination with OSS extractor allows fast, safe, accurate, precise and cost-effective quantification of oil and grease in wastewater at ppm levels in a few minutes. No hazardous chemicals are used in the analysis, no need for chemical explosion fume hoods, no additional glassware nor sensitive balances.
In addition, FT-IR spectroscopy enables tracing the origin of the contamination, hence providing crucial and timely information to stop the contamination from becoming larger or from happening again.

Introduction
Honey is the natural sweet substance, produced by Honeybees from the nectar of plants. Honey has a superior nutritional value and contains a variety of minerals that are minor constituents. Elements such as Cu, Sn, and Zn are essential for normal metabolism in human and elements such as Pb, Cd, As and Hg are considered as toxic and harmful to human metabolism. Mercury (Hg) is considered as an element of concern for major public health by the World Health Organization (WHO)1). Methylmercury (CH3Hg) is the most common and toxic organic form of mercury. The source of these toxic elements could be from air pollution, pesticides, industrial waste or natural disaster which goes from ground water to soil and then from plants nectar to Honeybees.
The potential for mercury contamination has become serious concern to human and environmental health. The contamination of mercury and its conversion to methylmercury is largely depending on the location in which it arrives. If the location is favorable, then the conversion of inorganic mercury to the significantly more toxic organic form of methylmercury happens.
The Food Safety and Standards Authority of India (FSSAI) has laid down limits of 1.0 mg/kg for total mercury and 0.25 mg/kg CH3Hg in food products2). To meet these limits ICP-MS is widely used as an accurate and reliable technique for quantification. In the present study, one honey sample was analyzed using Shimadzu ICPMS-2030 for quantitation of total and inorganic mercury along with quantification of methyl mercury by coupling ICPMS-2030 to HPLC as a speciation technique.
Conclusion
The present work demonstrates the suitability of the HPLC-ICP-MS method for the quantification of inorganic mercury and methylmercury in honey, in accordance with FSSAI regulations. The inorganic and methylmercury forms of Hg were measured accurately at low-ppb concentrations in honey sample using a Shimadzu Inert HPLC LC-20Ai coupled to a Shimadzu ICPMS-2030. The separation of both species was complete in less than five minutes. LabSolutions TRM software can perform LC and ICP-MS measurements. ICPMS-2030 enables quantitative analysis of elements essential for normal metabolism such as Cu, Sn and Zn and toxic trace elements such as Pb, Cd, As and Hg in honey. Excellent detection limits were obtained using Shimadzu ICPMS-2030 with unique mini-torch technology which uses lowest argon flow rates as compared to any other conventional ICPMS.
