Sample stacking effects and large injection volumes in micellar electrokinetic chromatography of ionic compounds : direct determination of iso-α-acids in beer

, 1993
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
