Gas analysis chromatograph

liquefied gasGas, coal gas, and other gasesThe analyzer isShanghai Xuansheng Scientific Instrument Co., LtdA small developed productgasGas analysis instruments can detect the content of methane, ethylene, ethane, propylene, propane, dimethyl ether, isobutane, n-butane and other components in liquefied gas through a single sampling injection; Very suitable for liquefied gas stationsGas stations, point supply stations, etc.

☆ Analyze the composition and detection limit

gasThe analyzer is suitable for analyzing gaseous hydrocarbons below C5, excluding alkynes. Ingredients: air, methane (CH4), ethane (C2H6), ethylene (C2H4), propane (C3H8), propylene (C3H6), isobutane (iC4H10), n-butane (nC4H10), n-butene (1-C4H8), isobutene (iC4H8), butene (cC4H8), isobutene (tC4H8), 1,3-butadiene, n-pentane (C4H10), isopentane (C4H10) Concentration range: 100PPm~50%

☆ Instrument features

◆Gas analysis chromatographMade in China with the first generation high-performance and high stability GC-7890Based on chromatography, it operates reliably and stably.

Adopting a dual gas six way valve, dual packed column separation, and manual injection, all the above components can be fully analyzed with one injection.

◆ Single wire micro thermal conductivity detector (TCD) can also be used for detection, with a large caliber 0.53mm PLOT capillary column for separation.

◆ Optional 8-liter aluminum bottle standard mixture for easy analysis and quantification.

◆ Dual channel chromatography workstation, supporting Windows 98/2000/XP operating system, allows for free storage, data processing, and report printing of chromatographic analysis spectra.
