GC-2000
GC 2000 Gas Chromatograph
A gas chromatograph with electronic gas control accurate to 0.001 psi and support for up to four detectors at once. Its flexible valve system handles complex gas analysis, and everything is controlled from an 8-inch touch screen.
Key Features
- Environment: Analysis of methane and non-methane total hydrocarbons (HJ 604, HJ 38) and 116 VOCs in a single injection, without cooling the oven
- Food and drugs: Pesticide residue analysis by GC-MS/MS, for example 208 pesticides per GB 23200.113-2018
- Energy and chemicals: Analysis of non-condensable gas, natural gas, coal gas and refinery gas with multi-valve, multi-column configurations; pressurised liquid samples can be injected through the high-pressure liquid valve
- Public security and forensics: Blood ethanol determination by dual-channel headspace per GA/T 842-2019
