Analysis of PFAS Specified in EPA Method 537 and Beyond using Shimadzu UFMS
This application note demonstrates the use, performance, and compatibility of Shimadzu ultra-fast mass spectrometry for EPA Method 537 with an expanded compound panel of seven additional PFAS. A total of 27 PFAS were extracted, separated and detected with triple quadrupole mass spectrometers, LCMS-8045 and LCMS-8050. Recoveries of 86-106% (LCMS-8050) and 77-104% (LCMS-8045) were well within the limits outlined in EPA 537. Method detection limits of 0.7-1.7 ng/L (ppt) and 0.7-3.3 ng/L were obtained and both systems fulfilled all of the EPA's requirements for PFAS analysis in drinking water.
