Leakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method is designed for early detection to prevent coolant from accumulating and seriously damaging the engine

ASTM D4291 Trace Ethylene Glycol In Used Engine Oil By GC

KN-4291 GC for Trace Ethylene Glycol in Used Engine Oil

Overview
The sample of oil is extracted with water and the analysis is performed on the water extract. A reproducible volume of the extract is injected into a gas chromatograph using on-column injection and the eluting compounds are detected by a flame ionization detector. The ethylene glycol peak area is determined and compared with areas obtained from the injection of freshly prepared known standards.

Introduction:

KN-4291 GC conforms to ASTM D4291 Standard Test Method for Trace Ethylene Glycol in Used Engine Oil. It is used for the measurement of ethylene glycol as a contaminant in used engine oil. The ethylene glycol is supposed to be in the range from 5 to 200 mass ppm.

Standard Calibration:

Prepare glycol standards over the quantification range of 0.01% to 0.2% w/w in motor oil

Temperature information:

Temperature range: Ambient+5℃~ 400℃, Increment: 0.1℃
Accuracy: ≤±0.1℃
Programmed heating: Constant temperature time between five steps 0~999min, increment: 0.1min, temperature increment: 0.1℃
Heating rate: max. 40℃/min below 200℃
max. 20℃/min above 200℃
