Simultaneous Analysis of Inorganic Gases and Light Hydrocarbon Gases

When analyzing the purity and composition of gases, the analysis of concentrations (on the order of several ppm) difficult for a TCD conventionally required a complicated system combining a methanizer and FID, and that is equipped with a pre-cut mechanism. The Shimadzu system can simultaneously analyze inorganic gases and light hydrocarbons using a simple configuration with a suitable column connected to a BID.

If the hydrogen fuel used in fuel cells contains carbon monoxide or other impurities, this will toxify the catalyst used in the cell, reducing the catalytic performance. Accordingly, high-purity hydrogen fuel is required. A high-sensitivity analysis system for inorganic gases based around the Nexis GC-2030 is capable of a dual-line configuration equipped with two BID units. Connecting two different columns enables a wide range of impurities to be quantified with high sensitivity in a single analysis.
