GC-3000 portable chromatograph

Product Description:

GC-3000 portable gas chromatographThe advanced microcomputer control system is adopted, which not only retains the advantages of the standard chromatograph, but also adds automatic protection for gas path faults, automatic ignition of detectors, and automatic execution of on-off gas path opening and closing functions. The whole machine adopts advanced gas path control technology (standard mechanical valve control, optional proportional valve), which greatly improves its automation level and overall performance; Adhering to the mature networked data transmission and processing functions of standard chromatography instruments, we provide industry leading analysis solutions!

GC-3000 portable gas chromatographA powerful chromatographic solution enables rapid, accurate, and reliable detection of gas samples, and provides * analytical methods for on-site and online samples. Suitable for rapid analysis of gases such as new energy, coal mine safety, power safety, environmental monitoring, automobile exhaust monitoring, petrochemicals, refinery gas, natural gas, oil and gas exploration, etc.
