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.

This method is recommended for the extraction of oligonucleotides from aqueous synthesis mixtures using a non-polar retention mechanism. See General Comments for more details on how this works.

The first decision that needs to be made is what the final analysis will be for the analyte. This will have an impact on the sample and cartridge size, as well as the final elution solvent. Gas chromatography offers higher sensitivity than HPLC, while HPLC is better suited for ionisable species and very high molecular weights. If LC-MS is available, minimal sample clean-up may be required.

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.

What is the maximum capacity of an SPE column?
The capacity of a sorbent is defined as the total mass of strongly retained analyte that can be retained by a given mass of the sorbent under optimum conditions.
For most sorbents, this can range from 1-5% by weight. 100 mg of sorbent might retain 1-5 mg of analyte.
Ion exchange sorbents typically have a capacity of 0.3-1 meq/g.Browse more questions and answers >
