Abstract

The molecular weight distribution (MWD) of the original and heat-treated Carbowax 20M and Pluronic F68 gas chromatographic stationary phases were determined by gel chromatography, and compared. The heat-induced changes in the MWD of Ploronic F68 were negligible compared with those in Carbowax 20M, even though the latter was heated to 30°C higher than Carbowax 20M. This finding supports previous observations concerning the superior stability of Pluronic phases in glass capillary columns. Glass capillaries coated with 0.25 μm Pluronic F68 were successfully used over a long period of time for essential oil analysis.
