Summary The possibility of using large injection volumes in micellar electrokinetic chromatography (MEKC) has been evaluated. With charged compounds effective focusing is observed. For a given liquid sample, the ratio of sample-to-buffer conductivity is decisive in obtaining this effect. The direct analysis of iso-α-acids in beer, thus omitting prior extraction, is demonstrated. Data on quantitative analysis are presented.
