Shanghai Gas Chromatography is a professional manufacturer of chromatographic analysis instruments, The SP-7890 natural gas analyzer is manufactured by Shanghai Gas Spectral Analysis Instrument Company specifically for the convenience of traditional analyzers and the tedious process of detecting natural gas The only one in the country that does not require setting and can complete methane, ethylene, ethane, acetylene, propylene, propane, isobutane, and n-butane in LNG/CNG/natural gas through a single injection; Accurate analysis of the content of more than ten components such as carbon dioxide or nitrogen.

An instrument that can directly perform LNG/CNG/natural gas analysis upon startup, without the need for professionals. Simple and convenient, easy to learn and understand, stable performance, and good value for money. One year warranty and lifetime free technical support. For a long time, it has been highly praised by new and old customers in the LNG/CNG/natural gas industry (especially gas wholesale, filling units, gas distribution stations, and large natural gas users), such as Xinao Gas, Hunan Baijiang Gas, Beijing CPC Gas, Nanshan Gas, Fujian Zhongran, etc.

Natural gas sales companies want to know if there is nitrogen in the purchased natural gas? How many? If nitrogen is to be mixed into natural gas, what is the content after mixing? What is the content of other components in the purchased natural gas? How much nitrogen directly affects the calorific value of the gas? As a LNG/CNG/natural gas sales enterprise, if these are not known, not only will it suffer economic and reputational losses, but it will also bring serious safety hazards to customers.
