Glycerol vs propylene glycol
WebNon-Polar Column Choice: The Equity-1. Poly (dimethylsiloxane) is a non-polar GC phase, and will not interact as strongly with polar compounds as a polar polyethylene glycol phase. As a result, retention will not be as strong, and tailing may be decreased. Figure 2 illustrates the separation on an Equity-1 column of the same mix shown in Figure 1.
