GC-4400 Portable Photoionization Gas Chromatograph

The GC-4400 Portable is a high-tech portable gas analyzer with independent intellectual property rights developed and commercialized in China. Integrating principles of physics, spectroscopy, electronics, analytical chemistry, precision machinery, new materials, advanced manufacturing, and integrated circuit technologies, the GC-4400 enables ultra-high-sensitivity analysis of trace-level chemical substances. It features low detection limits, a wide linear range, and requires no hydrogen or support gases. With direct sample injection and no need for pre-concentration, it offers non-destructive detection in a portable design. Suitable for monitoring volatile organic compounds (VOCs) as well as trace analysis of certain inorganic compounds。 The GC-4400 is widely used in: Atmospheric and environmental pollution incident monitoring Indoor environmental pollution assessment Food safety Agriculture and ecology National defense, chemical protection, and counter-terrorism Aerospace Scientific research and new product development Other fields requiring trace gas/vapor analysis
