Analysis of the perfluorinated alkyl acids listed in EPA Method 537 along with fluorotelomeric alcohols and perfluorinated sulfonates were extracted using SPE (using ISOLUTE 101 500 mg/ 6 mL SDVB SPE columns) 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.

Perfluorinated chemicals (PFCs), also known as PFAAs, can be found in commercial and industrial uses such as firefighting foams, package material coatings, nonstick cookware, waterproofing and stain proof fabrics. PFCs are all manmade and have unique properties such as repelling water, oil and heat. They are very difficult to break down and persist in the environment.
