Gas Chromatograph

Features:
  • 5.7-inch LCD display indicates temperature, time, and gas flow.
  • Can install packed column and capillary column at the same time                                                                             
  • Self-test, power protection, keyboard lock, automatic ignition and anti power mutation interference function
  • With chromatography workstation software to process data.
  • Equipped with a flame ionization detector (FID), and TCD, ECD, FPD, NPD are optional. Can install 3 detectors at the same time.
  • Can connect with Internet, realize data transfer, and program upgrade automatically.                                 ””
  • Double column compensation function, which can effectively restrain baseline drift and the influence of background noise
  • Large capacity oven (300*2B0*180mm) can hold 2 pcs 0.32mm diameter capillary column (length: 80m).
  • Better thermal insulation effect. when the temp. of oven, vaporizing chamber and detector reach 300°C, the max. temp. of outer chamber is 40°C.
