The analytical methodology for low concentrations of PFOA is quite involved
and requires a double mass spec. 19C.
L
Our site does not have the analytical capability to do this analytical
method. To my knowledge, there are no North Carolina labs who can do the
analysis.
DuPont exclusively uses Exygen Research in State College, PA to do the
analysis of all water samples. Their phone number is 814-272-1039.
EPA has a laboratory somewhere that can analyze for PFOA, but their lab
doesn't have the sensitivity of Exygen.
Let me know if you need more information.
