This poster presents an example of the analysis of all 17 explosives listed in EPA 8330B using atmospheric pressure chemical ionization liquid chromatography mass spectrometry (APCI-LC-MS/MS), which allowed for more sensitive and selective analysis than PDA detection. In addition, MRM analysis provides an extra layer of confirmation based on the unique fragmentation of each compound.

This poster presents a comprehensive, multi-approach data processing method for the analysis of non-targeted PFAS in both positive and negative ionization modes. Results show this three-pronged approach gave comprehensive identifications without excess false positives.

This poster shows the development and validation of a fully automated sample preparation and subsequent LC-MS/MS with trap-and-elute chromatography assay analyzing 25-hydroxyvitamin-D2 and D3. With this automated platform, technicians can significantly reduce their active time in the sample preparation workflow, focusing primarily on sample registration and results review.

EPA Method 1633A is currently the only validated multi-lab method for PFAS detection in leachate. This poster demonstrates the effectiveness of a system to provide robust, stable performance over 154 injections and 37 hours of continuous PFAS analysis, making it ideal for routine monitoring of complex leachate matrices.

Cannabinoid separation can be difficult with the presence of coeluting isomers. This application shows how a combination of LabSolutions MD (Method Development) software and powerful i-PDeA technology can help determine the optimal method for cannabinoid separation and deconvolute remaining co-eluting peaks after optimization.

This application showcases how a compact, affordable single quad LCMS can be easily integrated into existing laboratories for measurement of PFAS in diverse samples where adherence to regulated methods (e.g., EPA 533, 537.1, and 1633) is not required, or samples where expected concentrations are larger than sub ppb levels.

This application news presents instrument operating conditions and instrument method performance statistics, including method linearity, accuracy, and precision, for priority pollutant pesticides and PCB congeners. The method validated in this application acted as guidance in developing ASTM D8543 Test Method for Determination of OCPs and PCBs in Aqueous Solution by a GC/MS/MS which is intended for proposal to EPA as an alternative test procedure (ATP) for EPA 608.3
