Gas Chromatograph 2

Features
1． 5.7-inch lcd display indicates temperature, time and gas flow.
2． self-test, power protection, keyboard lock , automatic ignition and anti power mutation interference function.
3． can connect with internet, realize data transfer and program upgrade automatically.
4． equipped with a flame ionization detector (fid), and tcd, ecd, fpd, npd are optional. Can install four detectors at the same time.
5． can install packed column and capillary column at the same time
6． double column compensation function, which can effectively restrain baseline drift and the influence of background noise.
7． large capacity oven (300*280*180mm) can hold 2 pcs 0.32mm diameter capillary column (length: 80m).
8． better thermal insulation effect: when the temp. Of oven, vaporizing chamber and detector reach 300℃, the max. Temp. Of outer chamber is 40℃.
10. With chromatography workstation software to process data.
