A method for conversion of the universal detector signal in isotachophoresis which enables the use of conventional chromatographic integration procedures is introduced. A microcomputer monitors the detector signal at 48 Hz with an 8-bit accuracy. The converted signal is stored in the computer memory and can be processed as if it were a chromatogram. The computer program was evaluated with a series of test mixtures and applied in the determination of anions in wine and urine.
