High purity gas analysis specific gas chromatography

Analysis of trace impurities in high purity gases has been difficult chromatographic analysis. At present, the majority of high-purity gas analysis using thermal conductivity (TCD) detector due to the limited sensitivity, it is difficult not to meet the basic requirements of high-purity gas analysis. With the domestic development of high-purity gases and gas industry users of the increasingly high demand for gas purity, over several detectors have been unable to complete the detection of trace impurities in high purity gases. Days spectrum Instruments research and production of high-purity gas analysis chromatograph equipped with special detectors, for almost all of the inorganic and organic compounds that have a high response, especially suitable for the analysis of permanent gases. Features: All Chinese interface, intuitive and simple operation of the gas chromatograph Chinese interface, instrument setup prompt use graphical man-machine dialogue, setting the analysis conditions in a short time. High accuracy, wide range of oven temperature control microcomputer temperature control, temperature control and high precision, stable and reliable. It has six fully independent temperature control system, the oven can achieve five stage temperature programming; provided with an automatic rear door structure, near room temperature control heating and cooling speed. While preserving the ten sets of ten sets of analysis parameters stored analysis parameters file way, long-term storage in case of power failure; and to call the file, initialize, and the save operation. A variety of options designed to meet the needs of different analytical instrument has a double column double air way, you can install two three injector and detector: hydrogen flame and thermal conductivity; also can be installed dihydrotestosterone flame or dual heat conduction. Can easily achieve the packed column injection, wide-bore capillary column direct injection and small-bore capillary split injection conversion. According to the analysis required and optional split / splitless injector, gas sampling valve, reformer, cracker, headspace sampling, thermal desorption injector and the like.
