| Abstract: | 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. |
