GC-4400 Portable Photoionization Gas Chromatograph

The GC-4400 Portable Photoionization Gas Chromatograph is a portable photoionization gas detector with independent Chinese intellectual property rights that has been industrialized in China. The GC-4400 is a high-tech product integrating multiple disciplines such as spectroscopy, electronics, analytical chemistry, precision machinery, new materials, new processes and integrated circuits based on physical principles. It can achieve ultra-high sensitivity analysis of trace chemical substances. It is a portable gas detector with low detection limit, wide linear range, no need for hydrogen and combustion-supporting gas, direct injection without pre-enrichment, non-destructive and portable. It can be used for both volatile organic compound (VOC) detection and trace analysis of some inorganic compounds. It is widely applied in atmospheric environmental pollution accident monitoring, indoor decoration environmental pollution monitoring, food safety, agriculture, ecology, national defense chemical protection and anti-terrorism warfare, aerospace, scientific research and new product development, as well as other departments requiring trace gas (vapor) analysis.
