Tengzhou Zhongke Spectral Analyzer Co., Ltd. has developed a new method and related equipment for rapid detection of dimethyl ether components in liquefied gas for gas companies and the petroleum liquefied gas industry. Through a single sampling injection, it can complete the detection of methane, ethylene, ethane, propylene, propane, isobutane, n-butane and other gaseous hydrocarbons below C5 in liquefied gas (excluding alkynes). At the same time, it can also detect the content of dimethyl ether mixed in liquefied gas; Very suitable for controlling the content of liquefied gas in liquefied gas stations;

Configuration of dimethyl ether analyzer for liquefied gas: TCD+double packed column+single six way valve injection+hydrogen gasGenerator+instrument workstation (acquisition software).

Regional sales, note: Our company sends technical personnel for free installation, start-up, and commissioning after sales, responsible for professional training of experimental personnel, implementing a "turnkey" project. The whole machine is guaranteed for one year and maintained for life.

The instrument complies with national standards:

(1) GB 10410.3-89 "Gas Chromatography Analysis of Liquefied Petroleum Gas Components"

(2) SH/T 0230-92 "Determination of Composition of Liquefied Petroleum Gas (Chromatography Method)"

Analysis spectrum of dimethyl ether in liquefied gas: (￠ 3 * 6m)
