Recovery of internal std in SRM-1957


ABSTRACT: Validation of XLE quantification using standard reference material. High recovery of [13C] labelled chemicals was obtained for important classes of environmental chemicals (PCB, PBDE, PAH, chlorinated pesticides) in NIST SRM-1957. Recoveries ranged from 110±7% for [13C10]mirex to 91 to 105% for congeners of universally [13C] labeled PCBs, PBDEs and chlorinated pesticides, with only [13C12]p,p’-dichlorodiphenyldichloroethylene (p,p’-DDE) having low recovery of 65±6%. Therefore, the simplified extraction procedure provides an efficient recovery of environment chemicals in an organic phase.
