Analyzing Impurities in Ammonia and Source Gases

Impurities in the hydrogen and nitrogen source gases used to produce ammonia, as well as impurities in ammonia itself, were analyzed. By using a system GC, these gases can be measured reliably at low concentrations. Adopting a pretreatment system that selectively analyzes impurities using multiple analytical columns enables stable, long-term continuous analysis.
