Notes:
A simple isotachophoretic (ITP) preconcentration column for subsequent online capillary zone electrophoresis is described, and its use for enhancing detectability in capillary zone electrophoresis (CZE) is evaluated. Sample preconcentration using ITP is shown to enhance detectability in CZE by several orders of magnitude. Experimental verification of the detectability gain is demonstrated for cationic and anionic separations; an increase in detectability of more than 200-fold was achieved. The practical applicability of this method is demonstrated using a direct analysis of thiamine in human blood.
