A reproducible pyrolysis gas-chromatographic system for the analysis of paints and plastics

Abstract

A system is described that will permit inter-laboratory comparisons of pyrograms, a method rarely used in the past owing to difficulty in obtaining satisfactory reproducibility. After investigation of various pyrolysers and column packings, a Curie point pyrolyser and a solid-phase packing, Porapak Q, were chosen as being the most suitable.
