Abstract:
Volatile additives for vulcanized or unvulcanized rubber can be accurately identified by controlled heating of a test sample in a sealed vial equipped with an overhead collecting headspace, transferring the heated volatiles to a chromatograph column, and analyzing the separated volatile components emerging from the chromatograph column by various selective analytical detectors.
