Using a convenient mobile phase (1 mM o-phthalic acid-TRIS buffer/acetonitrile), an ion chromatographic system is proposed for analysis of main inorganic anions (chloride, nitrite, bromide, nitrate, phosphate, sulfate) in natural waters by using indirect photometric detection. The main reason for the detector choice was that UV detectors are widespread in educational and low level equipment laboratories. Indirect photometric detection is an attractive and inexpensive approach and the system is versatile.

Key words: Ion chromatography / natural water / conductivity detection / indirect photometric detection.
