Capillary column measurement of glycol in in-use engine oil
Capillary column measurement of glycol in in-use engine oil Details:

Name: Capillary Column
Stationary phase: polyethylene glycol
Specification: 15m0.53mm*2um
Model: PEG-20M
Application: Determination of trace glycol in used engine lubricating oil by gas chromatography

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a gas chromatography-FID detection method for the determination of in-use engine oil by referring to ASTM D4291-04 (09) "Determination of Trace Glycol in Used Engine Lubricants by Gas Chromatography" The method of ethylene glycol content. The engine oil sample was diluted with n-ethane and then extracted with water, and then determined by gas chromatography.
