Fully automated, intelligent, high-throughput elemental analysis of drinking waters using SQ-ICP-MS

Learn about a robust, fully automated, high-throughput analysis of environmental samples, according to the requirements of US EPA method 200.8 Revision 5.5. This method uses a Thermo Scientific iCAP RQ ICP-MS coupled to an intelligent autodilution system, which automates much of the sample preparation and data review. It performs automatic re-runs of samples that do not meet predefined limits, thus significantly decreasing the cost and time to reportable results. The entire analysis (encompassing sample dilution, calibration and measurement) can be run with minimal manual intervention.

US EPA SW-846 Method 6010D using the Thermo Scientific iCAP 7400 ICP-OES Duo

Simplify and shorten analysis time per sample while maintaining compliance and exceeding the requirements of US EPA Method 6010D with ICP-OES. This study demonstrates the performance of the Thermo Scientific iCAP 7400 ICP-OES Duo for the analysis of environmental samples. The instrument achieves short analysis times while exceeding the requirements of the protocol. Its high-resolution optical system minimized spectral interferences and reduces stray light. Additionally, the advanced Charged Injection Device (CID) detector results in higher sensitivity and lower noise, which produces a high signal-to-background ratio. The simplified workflows of the Thermo Scientific Qtegra ISDS Software enable easy adherence to complex procedures using the automatic interference correction and quality control protocols. Using the method described, the time taken for each sample analysis was 2 minutes 35 seconds. This short analysis time leads to a low quantity of waste and low consumable requirements, minimizing both the cost of analysis and its environmental impact.

Direct analysis of environmental samples using ICP-MS with argon gas dilution (AGD)

Discover a method to meet the challenge of analyzing high-matrix samples for trace elements using an ICP-MS system equipped with argon gas dilution (AGD) for routine analysis of ultratrace multi-elements in complex samples. This study demonstrates the performance of a Thermo Scientific iCAP RQ ICP-MS with AGD for direct, high-throughput analysis of trace elements in sea water, wastewater and drinking water. Spectral interferences were eliminated using kinetic energy discrimination (KED) with pure helium as the collision gas. Total run time per sample was just 2 min 10 s, allowing for fully quantitative measurement of 14 elements, including sample uptake and washout, enabling a significant boost in laboratory throughput. Comprehensive, ultratrace multi-element analysis, including beryllium, was achieve without sacrificing sensitivity or robustness of the system.
