Using an Automated Micro-Scale Chamber Coupled Directly with the Analysis System

An automated analysis system consisting of a dynamic headspace (DHS) system coupled with thermal desorption-Gas Chromatography/ Mass Spectrometry (TD-GC/MS) was used for fully automated microscale chamber material emission analysis of Spray Polyurethane Foam (SPF). Closed-cell and opencell SPF samples were analyzed for emissions of TVOCs and high boiling compounds such as, for example, flame retardants and amine catalyst. Foam samples were analyzed qualitatively, and 15 hour emission tests subsequently carried out to investigate off-gassing mechanisms of the foams.
