Gas Chromatograph


Gas chromatography (GC) is mainly used for the qualitative analysis of samples: it answers the question “What chemicals are present in this sample, and in what relative proportions?” The basic idea with GC is that you inject a liquid into a long coil (or column) which is contained in an oven. Because oven heats the coil the liquid will vaporize. Because the coil is long it will take the vapors some time to reach the end of the coil. Different vapors will exit the coil at different times. We can compare these times to standard values to determine the identity of the vapors, and therefore, the chemicals that were in the sample.

5.7-inch LCD display indicates temperature, time and gas flow.Self-test, power protection, keyboard lock, automatic ignition and anti power mutation interference function.Can connect with Internet, realize data transfer and program upgrade automatically.Equipped with a flame ionization detector (FID), and TCD, ECD, FPD, NPD are optional. Can install four detectors at the same time.Can install packed column and capillary column at the same timeDouble column compensation function, which can effectively restrain baseline drift and the influence of background noise.Large capacity oven (300*280*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 300ºC, the max. temp. of outer chamber is 40ºC.
