Standard Test Method for Impurities in Monoethylene Glycol by Gas Chromatography with Normalization

Importancia y uso:

4.1 This test method is suitable for setting specifications and for use as an internal quality control tool where these products are produced or are used. Typical impurities are: 1,3-dioxolane-2-methanol, diethylene glycol, and triethylene glycol.

4.2 This method may not detect all components and there may be unknown components that would be assigned inappropriate relative calibration factors and thus, the results may not be absolute.
