Gas chromatography

Hewlett-Packard 5890 Series II gas chromatograph

This Hewlett-Packard 5890 Series II gas chromatograph includes two different inlet systems, a combined split/splitless capillary inlet with back-pressure regulation and a cool on-column inlet with electronic pressure control (EPC). Either a flame ionisation detector (FID) or a nitrogen-phosphorous detector system can be used.

The gas chromatograph system is coupled to a Hewlett-Packard Chemstation data processing system.

The Headspace gas chromatograph-mass spectrometer

This configuration consists of a Hewlett-Packard GC-MS-DS performance system which includes a HP6890 gaschromatograph, a HP5973 mass selective detector with turbo-pump mainframe and a suitable data processing unit. The PTV-injector is a Gerstel CIS-4 cooled injection system, used with liquid nitrogen for trace enrichment.

Furthermore a Gerstel multipurpose sampler (MPS), including a 100 sample tray, is present (mostly used in head-space mode).
