Shimadzu has released GC Driver Ver. 2.2 with Thermo Scientific™ Chromeleon™ Compatibility
Chromeleon chromatography data systems can now be used to control AOC-30 autoinjectors in Shimadzu Nexis™ GC-2030 systems and perform packed column analysis.
High-Sensitivity Analysis System for Inorganic Gases
Gas containing inorganic gases and hydrocarbons is typically analyzed in any number of industries using a gas chromatograph (GC). Generally speaking, either a flame ionization detector (FID) or a thermal conductivity detector (TCD) is selected depending on the type and concentration of the gases being analyzed. However, a gas analysis system equipped with a barrier discharge ionization detector (BID) can analyze almost any component except helium (He) and neon (Ne) with high sensitivity.
The Shimadzu high-sensitivity analysis system for inorganic gases can simultaneously analyze light hydrocarbons and low-concentration inorganic gases, including atmospheric components such as oxygen and nitrogen. It utilizes a gas sampler equipped with a purge mechanism to prevent contamination by air, and a special splitter. Because of its versatility, this system improves laboratory productivity by accommodating a wide range of gas analyses.
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.

Analysis of Trace Impurities in Pure Gases
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.
O2: Approximately 100 ppm, N2: Approximately 340 ppm, Other Components; Approximately 0.2 ppm
O2: Approximately 25 ppm, N2: Approximately 160 ppm, CO2: 0.44 ppm, Other Components; Approximately 0.2 ppm
