Notes:
This paper reports on the instrumental and experimental prerequisites of the combination of high temperature gas chromatography (HTGC) with electron impact- (El) and chemical ionization (Cl) mass spectrometry (HTGC/EI/CIMS). It describes a newly developed high temperature GC/MS interface in detail and discusses the particular problems arising in HTGC/MS. The capabilities of the system are demonstrated by direct analyses of nickel- and vanadyl porphyrins, extracted from Julia Creek oil shale. The use of CI/NH3 in the GC/MS analysis of metalloporphyrins is demonstrated for the first time.
