A simple and rapid procedure for the purification of indole-3-acetic acid prior to gas chromatography-selected ion monitoring-mass spectro-graphic analysis was developed using an amino anion exchange minicol-umn and a short high resolution C18 column. Since multiple samples can be prepared at one time, the procedure is more rapid and the sample preparation time is reduced to one-third that normally required. In ad-dition, the final recovery was improved by 40 to 50% over that of a solvent partitioning procedure.
