The GB/T 42238-2022 standard focuses on the field of surfactants and specifies the determination of free propylene oxide in propylene oxide coalescence surfactants by Gas chromatography, CG. It provides detailed instructions on the parameter setting of Gas Chromatograph, sample preparation and processing, test steps and result calculation. Through this standard, the free propylene oxide content can be accurately detected, and the product mass can be controlled. It is of great significance to surfactant production, mass monitoring and related application industries, which can effectively ensure product performance and safety.
