WebDimethoxyethane, also known as glyme, monoglyme, dimethyl glycol, ethylene glycol dimethyl ether, dimethyl cellosolve, and DME, is a colorless, aprotic, and liquid ether that is used as a solvent, especially in batteries. [2] Dimethoxyethane is miscible with water . 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.
