Abstract
The variation of thermal conductivity with temperature for gaseous species is studied here to investigate if an improvement of the specificity can be achieved with a field TCD-based gas chromatography system. However, theoretical predictions as well as experiments indicate that the necessary local analyte concentrations are by far (two orders of magnitude) beyond the typical concentrations encountered by portable trace analyzers.
