Food grade nitrogen dedicated chromatographSuitable for detecting trace impurities in high-purity gases. This product is equipped withFID and ZD; using six or ten way valves with blowdown protection air circuit; Together with components such as carrier gas purifiers and dead volume sampling valves, a complete high-purity gas analysis system and solution are formed.
Food grade nitrogen dedicated chromatographEquipped with non dead volume sampling valve and dedicated pressure reducing valve for carrier gas. The use of injection system pressure protection and leak prevention technology, as well as central cutting and blowback systems, can be used to detect trace impurities in high-purity gases such as high-purity nitrogen, high-purity helium, high-purity carbon dioxide, high-purity argon, krypton, xenon, neon, and electronic industrial gases such as silane. One injection, dual channel simultaneous analysis,Results can be obtained in 3 minutes.

1. Adopting a 4.3-inch touchscreen LCD Chinese display, with real-time display of various temperatures and operating conditions,
2. Power on self-test, five independent temperature control channels;
3. If any sensor circuit breaks, the instrument will automatically display an alarm;
4. High precision dual stable gas path, capable of installing up to four detectors simultaneously;
5. The four-way external event function supports multi valve switching;
6. Optional electronic flow pressure display system and built-in workstation device.
