Abstract

Abstract A method for the determination of vinyl chloride residue in poly(vinyl chloride) using a commercial purge-and-trap ancillary unit has been developed. Concentrations lower than 10ppb (10 9) with relative standard deviations in the region of 10% in up to 24 samples are detectable with fully automatic operation without operator attendance. With multiple extraction of the same sample an external standard is used; the matrix does not any influence on the recovery of vinyl chloride.
