China Education Equipment Purchasing Network News: According to the Shanghai Instrument Industry Association, the GC126-PID gas chromatograph photoionization detector independently developed by Shanghai Precision Scientific Instrument Co., Ltd. has recently passed the type evaluation of the Shanghai Metrology Institute. This product has independent intellectual property rights and has been authorized by the State Patent Office for invention patents.
Jingke's GC126-PID gas chromatograph developed by the "Mass Spectrometry Development Team" has high selectivity and analytical sensitivity for benzene and carbonyl-containing compounds; the sensitivity is 50-100 times higher than that of FID. Connected with capillary tube, it overcomes the disadvantages of traditional packed column such as easy loss and low column efficiency. It has wide linear range and can detect benzene series of 0.5ppb-500ppm in the environment. Its main performance index has reached the international standard of similar detectors. The product is equipped with corresponding instruments. One can monitor benzene, toluene, ethylbenzene, xylene, styrene, formaldehyde and acetaldehyde in the atmosphere; two can monitor automobile exhaust (nitrogen oxide); three can detect organic solvents in food Residual (solvent No. 6) and freshness analysis of food (mercaptan, thioether, hydrogen sulfide, etc.); Fourth, it can detect toxic gases (benzene, styrene, acetone, hydrazine, etc.) generated in the production of aerospace propellants.
The product can be used in combination with FID, mass spectrometry, infrared detectors, etc. to obtain more information. It has no radiation, no hydrogen or combustion gas, and can use high-purity nitrogen or air as the carrier gas without complicated chemical pretreatment ( Such as thermal analysis, etc.), safe and reliable, with the advantages of direct injection analysis.
