The effect of parameters - temperature, electricfield, concentration of analyzed compounds, type and composition of background electrolyte - on theseparation of analytes and precision of analysis was studied. The advantage of the elaboratedmethod is a very short time of analysis (2.3 min) at the sufficient level of precision and reliabilityof results.
