Abstract:
Summary A splitless Curie point pyrolysis inlet system for capillary columns has been built using conventional packed column apparatus. This has enabled the adsorption wire analysis system, for the rapid collection and direct GC analysis of vapours, to be used with capillary columns. Use of the technique for detecting traces of hydrocarbon fuels in arson investigation is described, as are problems occurring in its use.
