Determination of Polyethylene Glycols in Water by Reversed-Phase High-Performance Liquid Chromatography

This paper describes an RP-HPLC method to characterize the ozonation products of polyethylene glycols (PEGs) (general formula HO(CH 2CH 2O) n -H) with original mass 5000. Samples with different pH and ozonation times were studied. The amounts of individual products up to n = 56, the percentage of PE...
