Procedures have been developed that permit the routine reuse of open tubular columns for the analysis of fatty acid methyl esters. Cleaning techniques are given that permit essentially endless recycling of the expensive capillary tubing with nearly 100% success in obtaining excellent columns upon recoating when using polyester liquid phases. Cost, including preparation of column, is equal to or less than the usual conventional packed column. These procedures make it both practical and economical to take advantage of the improved resolution and the reduced time for an analysis obtained with the open tubular column.
