Summary

Supercritical fluid extraction (SFE) connected to open tubular gas chromatography has been used for the analysis of non-polar to medium polar volatiles entrained in polymers. This polymer sheets, prepared with the aid of a microtome, have been extracted with supercritical carbon dioxide. The influence of sample area/weight ratio and extraction cell volume on the SFE performance has been investigated. Further, quantitative analysis was executed by stepwise extractions.

A set of polybutylene terephthalate polymers, originating from different manufactures, has been analysed regarding entrained volatiles.
