Abstract:
A new technique for coupling capillary isotachophoresis (CITP) to Inductive coupled plasmas atomic emission spectrometry (ICP-AES) using flow injection (FI) is developed. Great attention to CITP have been paid owing to its broad application prospect in biochemistry, clinic, pharmacy, food,environment detection and conventional ionic analysis. Its zone-boundary sharpening, large size capillary and self-concentrating effects are different from those of other electrophoretic techniques. Recently, ICP-AES/MS, as a special metal detector, has been combined with the capillary zone electrophoresis (CZE). However, in CZE system, typical sample volume and flow rate are only in the range of 0.02 - 1 μl/min and 0.2-2μl, which results in the difficult for the coupling of CZE and ICP with conventional sampling system and the obtaining enough sensitivity.
