Draeger SF6 N2 Mixtures Analysis

Draeger SF6 N2 Mixtures Analysis

When complex mixtures (e. g. solvent mixtures), are present, usually only a laboratory analysis will suffice. The prerequisite is that the contaminated air is trapped in a sorbent sampling tube like silica gel or activated charcoal. After collecting the sample, analysis is performed in the laboratory with gas chromatographic methods, or ...

    Conference date: 23-26 Sept. 1996. Format: PDF. Two methods have been carried out for the analysis of SF6/N2 gas mixture decomposition by-products in electric discharges: infrared spectroscopy and gas chromatography. The infrared spectroscopy is a rapid method from which we can have qualitative analysis about all the products in a mixture, except those having the same absorption lines.
