The dedicated gas chromatograph for analyzing dimethyl ether in liquefied petroleum gas is suitable for the analysis of gaseous hydrocarbons below C5, excluding alkynes. Ingredients: air, methane (CH4), ethane (C2H6), ethylene (C2H4), propane (C3H8), propylene (C3H6), isobutane (iH10)/n-butane (nH10), n-butene (1-H8), isobutene (iH8), maleic (cH8), isobutene (tH8), 1,3-butadiene, n-pentane (H10), isopentane (H10)

We have developed a specialized gas chromatograph for the detection and analysis of dimethyl ether in liquefied petroleum gas. In accordance with the upcoming national standards, we have successfully developed a liquefied gas analyzer for this analysis task and developed corresponding detection methods. It can detect the components of liquefied gas and dimethyl ether mixed in liquefied gas. The analysis time is within 15 minutes, providing users with accurate and fast detection methods, as well as good training and learning opportunities and technical support.

Instrument configuration for dimethyl ether analysis in liquefied gas:
1. TCD+packed column injection system+six way valve injection)
2. Chromatography dedicated workstation (computer printer self equipped)
3. Chromatographic column: dedicated column for analysis of dimethyl ether in liquefied gas
4. Hydrogen generator
5. Random attachments
This configuration meets 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)"
