Trace determination of high molecular weight polyvinylpyrrolidone by pyrolysis-gas chromatography

Abstract The possibilities of using pyrolysis-gas chromatography as a technique for selective determination of polyvinylpyrrolidone (PVP) in trace quantities and the use of an appropriate detector such as a thermionic specific detector (TSD) have been investigated. However, the determination down to 0.2 ppm in the presence of polyhydric alcohols and high hydrophilic polymers such as polyethylene oxide was obtained with a flame ionization detector.
