Abstract

In this work we tried to clarify the relation between the signal detected by indirect UV mode and the concentration of the analyte introduced by electrokinetic (EK) injection from samples having small but different conductivities. A simple external calibration procedure was proposed for quantitative determination of traces that are present in low-conductivity samples. It was found that measuring the current through the capillary filled with the samples provides useful correction factor for the external calibration.
