Impurity Analysis in Bulk Gas

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.
Target compounds | Concentration |
H2 | 100 ppb |
O2 | 100 ppb |
N2 | 100 ppb |
CO | 100 ppb |
CH4 | 100 ppb |
CO2 | 100 ppb |

GC-2014 system is also available for some applications.
