Abstract

The width of the molecular weight distribution (MWD) of polymer stationary phases influences their polarity and other gas chromatographic characteristics. The MWD of the most frequently used polyglycol‐type stationary phases such as Carbowax, Ucon, Emulphor and Pluronic has been determined and compared. The MWD determined by gel chromatography allows for the characterization of the actual batch of a stationary phase, provides a check on its consistency and helps to screen out the apparently less promising phases.
