CE was recently used for anthocyanin analysis because of its excellent resolution. This technique has different modes capillary zone electrophoresis (CZE), capillary gel electrophoresis (CGE), micellar electrokinetic chromatography (MEKC), capillary electrochromatography (CEC), capillary isoelectric focusing (CIEE), and capillary isotachophoresis (CITP)."° CZE is the most popular method for anthocyanin... 

The comparative use of MEKC, CZE, and capillary isotachophoresis (CITP) for the determination of drugs in body fluids was reported by Caslavska et al. (1993). Salicylate, paracetamol, and antiepilectics in serum and urine were analyzed with the three techniques. In case of high drug concentrations, body fluids could be injected directly, or with simple dilution (for urine) or ultrafiltration (for serum). Extraction and concentration were necessary for... 

And CITP is favorably utilized in the analysis of low-molecular-weight ionic species. A difficulty often arises with finding suitable buffer systems that provide leading and terminating ions and also form the appropriate buffer pH. One of the advantages is that the capillary can be loaded with sample up to 30-50% of its length, enabling the analysis of very dilute samples. Furthermore, the principle of predetermined solute concentrations in isotachophoresis is also used as preconcentration step for very dilute samples prior to CZE, MEKC, or CGE.
