In automotive and industrial environments, the presence of ethylene glycol contamination within used engine oil serves as a critical warning sign for coolant leakage and imminent mechanical failure. For effective condition monitoring and proactive preventive maintenance, timely and highly precise detection is absolutely vital. However, conventional testing procedures like ASTM D4291-98 are typically labor-intensive and highly time-consuming, effectively bottlenecking sample throughput in busy routine laboratory settings.
To directly overcome these limitations, the GAS Ethylene Glycol Analyser introduces an innovative, high-efficiency analytical approach based on headspace gas chromatography. The process begins with the chemical derivatisation of ethylene glycol directly within the autosampler vial, which actively reduces its polarity while simultaneously increasing its volatility. Following a strictly controlled incubation period, a precise headspace volume is automatically injected into the system using the advanced Triplus headspace autosampler. Running on the dependable Thermo Trace GC1600 platform, this streamlined methodology provides an incredibly reproducible, low-maintenance solution for analyzing heavy engine oils.
