Abstract
A multiple parallel hand-held gas chromatograph (GC) system which includes several independent GCs. Each independent GC has its own injector, separation column, detector and oven and the GCs are mounted in a light weight hand-held assembly. Each GC operates independently and simultaneously. Because of different coatings in different separation columns, different retention times for the same gas will be measured. Thus, for a GC system with multiple parallel GCs, the system can measure, in a short period, different retention times and provide a cross-reference in the determination of the measured gas and to become a two-dimensional system for direct field use.
Claims19
A multiple, parallel hand-held gas chromatograph system, including:
- a plurality of independent gas chromatographs,
- said plurality of independent gas chromatographs being mounted in a hand-held carrier.
A hand-held gas chromatograph system comprising:
- a carrier having mounted therein a plurality of independent gas chromatographs mounted in at least one stack, a computer, a gas supply for said gas chromatograph, a power supply for said computer and said stack of independent gas chromatographs, at least one on/off valve for said gas supply, a pressure relief valve and a regulator for said gas supply, a gas inlet divider for said gas supply, and at least one pressure sensor for the independent gas chromatographs.
