Introduction to dimethyl ether detector and detection method for civilian liquefied petroleum gas: With the continuous rise of oil prices, the price of liquefied petroleum gas has also been increasing. As a clean fuel converted from coal, dimethyl ether has become an alternative product to liquefied petroleum gas and gradually shows its advantages. However, the addition of dimethyl ether to liquefied petroleum gas is already an open secret in the industry, so it is necessary and timely to intensify research on the detection methods and control measures of dimethyl ether in liquefied petroleum gas. Our company established a liquefied petroleum gas source testing laboratory in early 2008. I am responsible for testing and controlling the composition of liquefied petroleum gas and the dimethyl ether mixed in it. Through testing practice, I have explored a practical method for detecting the dimethyl ether content in liquefied petroleum gas.

At present, the technology of gas chromatography is developing rapidly. Tengzhou Zhongkepu is a professional manufacturer of liquefied petroleum gas packed chromatography columns or capillary chromatography columns and gas chromatographs. The chromatography columns produced by the company have good separation effect, stable quality, and long service life. The detector also uses more hydrogen flame detectors (FID), which have a sensitivity 10 times higher than thermal conductivity detectors (TCD). So now, gas chromatographs for detecting liquefied petroleum gas generally use packed columns or capillary columns, equipped with thermal conductivity detectors and hydrogen flame detectors. The former is generally used for external detection, while the latter is generally used for daily detection.

Ensuring gas supply safety and the interests of the company and users, the dimethyl ether detector and detection method produced by Zhongkepu for civilian liquefied petroleum gas play an indispensable role in the detection of dimethyl ether in liquefied petroleum gas. However, due to the drive of interests, a large amount of dimethyl ether is occasionally added to liquefied petroleum gas, so the detection and control of dimethyl ether is a long and arduous task.
