Liquid GC column for the analysis of glycerol from the mixture of steam reforming products

Please, I would like to know the appropriate column used for the analysis of glycerol especially the unreacted glycerol from the liquid mixture of steam reforming of glycerol?

Secondly, DB Wax UI columns have been suggested for the analysis of glycerol, however, the maximum temperature limits for these columns are 260 and 250 C for 0.25 um and 0.5um respectively. My questions are: considering the boiling point of glycerol (290C) for the development of GC method for the analysis, is it possible to bake-out or ramp-up the column to the temperatures higher than its limits?


Thank you
