The use of graphitized

FT has been extended to the analysis of phenolic compounds.

This has been made possible by coating the carbon surface with small amounts of a high-boiling, acidic liquid phase, such as FFAP. The effectiveness of this packing material in chromatographing phenols is made evident by the fact that cresols are separated in an analysis time of only 3 min and the fractionation of a mixture of more than twenty phenols is achieved by the use of a single column and with an elution time of not more than 45 min. By varying the liquid :solid ratio, the behaviour of gas-liquid-solid columns was studied.
