Analysis of Perfluorinated Compounds (PFCs)
GEL offers analysis of PFCs by EPA Method 537 Modified utilizing
LC/MS/MS technology and isotopic dilution to detect and differentiate the
compounds. GEL holds DOD ELAP IS017025:2005 accreditation for this
method, which is fully compliant with QSM 5.1 for analysis of PFCs. A
complete list of the 25 PFCs (including GenX) we offer and associated
limits are provided on the back of this document.
Our extensive history supporting the Department of Defense coupled with
our dedicated team of chemists makes GEL the right choice for meeting
your data quality objectives for projects requiring PFC analysis.
