Product Introduction
The GC-220 Flow and Pressure Monitoring Gas Chromatograph is a new generation of gas chromatograph with high stability and reliability, suitable for routine testing needs. It is equipped with an advanced electronic pressure and flow measurement and monitoring module. By adjusting the gas path knob, various gas parameters, including the pressure and flow rate of carrier gas, hydrogen, and air, as well as the inlet split ratio and column flow rate, can be easily obtained on the main unit display and workstation. No flow meter measurement or manual calculation is required, making operation extremely simple.
Applications and Detection Indicators
It can be widely used in various analytical fields such as petrochemicals, fine chemicals, biopharmaceuticals, environmental protection, food hygiene, high-purity gases, power, brewing, scientific research, and education, making it the best choice for daily testing.
