Scope

This document specifies spectrophotometric and liquid chromatographic methods for
the determination of aldehydes in ethylene glycol for industrial use.
This document applies to the determination of aldehyde content in industrial ethylene
glycol. The determination range is 0.10mg/kg~50mg/kg.
If the ethylene glycol sample contains ketones, the liquid chromatography analysis
results will be high. Therefore, when applying this document to the quality control of
the aldehyde content of ethylene glycol products, relevant parties shall negotiate to
determine the analytical method to be used.
