Petroleum liquefied gas analysis chromatograph

Petroleum liquefied gas analysis chromatographworking principle:

Component analysis of liquefied petroleum gas: using chromatographic separation method to complete the work. Due to the different components of the mixed gas, the length of time it stays in the chromatographic separation column varies, and the separation sequence is based on the order of gas weight from light to heavy. So this way, a detection instrument can be used to separate different gas components over time. By the order in which gas components are separated, we can know the names of various components in the mixed gas. Gas chromatograph for natural gas analysis, equipped with a two-stage pressure stabilization system, a six way valve injection system for packed columns, a thermal conductivity detector, and a gas analysis chromatographic workstation; It can achieve full analysis of hydrocarbon components such as oxygen, nitrogen, methane, ethane, carbon dioxide, propane, isobutane, n-butane, n-pentane, isopentane, and C6+in natural gas with a single injection.

According to the upcoming national standards, Shanghai Xuansheng Scientific Instrument Co., Ltd. has successfully developed a professional analyzer for the analysis of petroleum liquefied gas components and calorific value, and developed corresponding detection methods. It can detect liquefied gas components and dimethyl ether mixed in liquefied gas within 15 minutes, providing users with accurate and fast detection methods, as well as good training and learning opportunities.
