"Having acetoacetate, malate, citrate and some drug metabolites in untreated serum samples, the stacking mechanism of these compounds in an electrolyte system comprising 5 mM mandelic acid and e-aminocaproic acid (pH 3.8) is explained. Analytes are monitored by indirect UV absorption detection. Attention is paid to the minimum chloride concentration required with respect to the concentration ratio of phosphate (stacker) and lactate (destacker) present in the sample so as to ensure both stacking and separation of trace analytes. Insight into the separation process is given both with computer simulations and experiments. For selected analytes, the effect of the chloride concentration on quantitative evaluation, sensitivity and limit of detection is demonstrated as well." . "ICES 2001: An Electrophoretic Odyssey." . .
