Abstract
Some conditions for cation focusation on cation resin when using the microcolumn liquid chromatograph with conductometric detection are derived and verified experimentally. Separation is carried out using a complexing agent and a competitive cation in the mobile phase. Cations of transition metals, alkaline earths and lead were analysed. Sensitivity of the method ranges within tenths of p.p.b.Keywords
