✦ Synopsis
Gas chromatography Volatile polymers Polyethylene glycols Comparison between CPG and ofter methods
Identification of components and analysis of PEG mixtures, as well as the molecular weight determination, are of importance. This problem is difficult, and it requires the use of several different analysis methods. We attempted to show the efficiency and the sensitivity of gas phase chromatography by using Tenax as stationary phase, when the molecular weight of PEG mixtures is lower than 600. These results were compared with those obtained by using other methods such as viscosity, gel permeation chromatography and vapor pressure measurements.
