Trace Impurity Analysis
Impurity gas analysis is necessary in industries such as petrochemical, chemical, medical, and foods. Precisely controlled GC enables identification and quantitation of a trace amount of impurities in bulk gas. If the gas resources in a factory consist of multiple lines, a sample line selector can be utilized to switch sample lines automatically, allowing a single GC to analyze all samples.
