Main Instruments

This gas chromatograph uses four detectors and can detect a wide range of gasses with excellent retention time stability, with a high level of sensitivity even in samples with complicated matrices. This GC is also configured for measuring important greenhouse gases including methane, carbon dioxide, and nitrous oxide with high accuracy even at trace levels. 

The detectors include FID (Flame Ionization Detector), TCD (Thermal Conductivity Detector), ECD (Electron Capture Detector), and PDD (Pulse Discharge Detector). PDD is a high-sensitivity detector suited for the analysis of permanent gases (such as hydrogen, nitrogen, carbon monoxide), and allows for the detection of many trace impurities including methane, carbon dioxide, nitrous oxide, ethane, ethylene, and acetylene. The FID is used for detecting methane, the TCD detects carbon dioxide, and the ECD detects nitrous oxide allowing for the analysis of environmental samples for use in monitoring greenhouse gas levels.
