Interface for Coupling Capillary Electrophoresis to Inductively Coupled Plasma and On-Column Concentration Technique

摘要

A new interface for coupling capillary electrophoresis(CE) toinductively coupled plasma(ICP) was developed. The interface wasbuilt outside and indepentent of the nebu- lizer and could be easilyconnected with a microconcentric nebulizer(MCN) as well asconventional pneumatic nebu- lizers. An on-column concentrationtechnique was used to increase the sensitivity and to enhance theresolution of the system of capillary electrophoresis-inductivelycoupled plasma atomic emission spectrometry(CE-ICP- AES).
