摘要：

A binary pseudo-random injection of a sample containing low concentrations of common anions into the anion exchange column was used to enhance the signal-to-noise ratio of indirect UV detection of the ions. The detection limits obtained in our experiment (14 ppb, 14 ppb, and 64 ppb for Cl-, NO3- and SO42- respectively) are in good agreement with theoretical predictions. The large amplitude system peaks inherent to single column IC do not generate remarkable "ghost" peaks, which is indicative of the suitability of the input devices used in our studies.
