How to use gas chromatography for trace analyses

Trace gas analysis is generally the analytical technique used to determine the purity of a bulk gas. The actual quantitative level of the trace analysis is determined by a number of factors including system integrity, support gas purity, and detector sensitivity. Based on these elements, trace gases...

Description
Summary:Trace gas analysis is generally the analytical technique used to determine the purity of a bulk gas. The actual quantitative level of the trace analysis is determined by a number of factors including system integrity, support gas purity, and detector sensitivity. Based on these elements, trace gases (impurities in the bulk gas) are typically detected at the ppm (parts per million) or ppb (parts per billion) level.
