Abstract

Abstract: Anew interface for coupling capillary electrophoresis(CE) to inductively coupled plasma spectrometry(ICP-AES) was developed. The interface was independent .of the nebu-lizer, and can be easily connected with micro concentric nebulizer (MCN) and conventional pneumatic concentric nebulizer (CPCN). By CE-CPCN-ICP-AESand CE-MCN-ICP-AES,efficient separation of Cr³⁺ and Cr₂O₇^2-was obtained, and the sensitivity is satisfactory.

Key words: Capillary electrophoresis, Inductively coupled plasma spectrometry, On-line elemental speciation analysis
