ABSTRACT
The desirability of an ion chromatography technique using only water as the mobile phase is summarised by Small [1]. There are a number of ion chromatographic techniques that, though not widely used, deserve mention because of their simplicity and their potential for further development. A l l use water or another polar solvent as the sole component of the mobile phase. This not only eliminates the need for electrolytes and precise eluent make-up, but it avoids many of the detection problems that ionic eluents can impose. Detection can be expected to be very sensitive since the background is essentially deionised water.
