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.

Perfluorinated compounds (PFCs) are a group of compounds that have been used in a wide array of industrial and household applications, including fabric protectors, non-stick coatings for cookware, coatings for food packaging and in some fire-fighting foams.
Their persistence in the environment allows them to accumulate in water sources, particularly those used for consumption.
This work will demonstrate the use of a cartridge-based extraction
system to extract and quantify up to 24 PFC compounds in drinking
water to highlight the challenges associated with this application.
