High-purity gas is necessary in industries such as 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 SLS-2020 can be utilized to switch sample lines automatically, allowing a single GC to analyze all samples.

Analytical Example: Impurities in He

Impurities in He can be measured with a single analysis. This example shows an analysis with PDHID.
