GC-4400 Portable Photoionization Gas Chromatograph
The GC-4400 portable photoionization gas chromatograph is a portable photoionization gas detector with independent intellectual property rights in China and industrialized in the country. GC-4400, based on the principles of physics, is a high-tech product integrating multiple disciplines such as spectroscopy, electronics, analytical chemistry, precision machinery, new materials, new processes, and integrated circuits. It can achieve ultra-high sensitivity analysis of trace chemical substances. It is a gas detector with low detection limit, wide linear range, no need for hydrogen or combustion-supporting gases, direct injection without pre-enrichment, non-destructive and portable. It can be used not only for the detection of volatile organic compounds (VOCs), but also for trace analysis of some inorganic compounds. It is widely applied in fields such as monitoring of atmospheric environmental pollution accidents, indoor decoration environmental pollution, food safety, agriculture, ecology, national defense and chemical defense and counter-terrorism wars, aerospace, scientific research and new product development, as well as other departments that require trace gas (vapor) analysis.
