Scope
This part of GB/T 14571 specifies the principles, reagents or materials, instrumentation and equipment, samples, test procedures, test data processing, precision, quality assurance and control, and test reports for the determination of purity and impurities in industrial glycol by gas chromatography. This part is applicable to the determination of industrial glycol samples with a purity of not less than 98.0% (mass fraction). Among them, the detection limits of 1,2-propanediol and triethylene glycol are 0.0020% (mass fraction), and the detection limits of 1,3-propanediol 2-methanol, diethylene glycol, 1,2-butanediol, 1,4-butanediol, 1,2-hexanediol, and ethylene carbonate are 0.0010% (mass fraction).
