Analysis of PerfluorinatedAlkyl Acids Specified in EPA M537 and Beyond Using the Triple Quad LCMS-8045

Introduction

Analysis of the perfluorinated alkyl acids listed in EPA Method 537 along with fluorotelomeric alcohols and perfluorinated sulfonates were extracted using SPE and analyzed on the LCMS-8045. Minimum Detection Limits (MDL) ranged from 0.69 to 3.25 ppt. Extraction recoveries were greater than 80% for all compounds, with surrogate recoveries within 10% of the true value.
