Advances in column technology and instrumentation in capillary electrochromatography.
Capillary electrochromatography (CEC) is an emerging technique gaining increased interest. Improvement of instrumentation and column technology will be of prime importance for the further development of this technique and its use in validated methods. In this paper, developments in column technology and instrumentation for CEC are reviewed with emphasis on developments within the last 3 years. Attention is directed to the employment of stationary phases specifically designed for CEC, the use of soft and rigid gels in place of packings, fritless packed capillaries, column dimensions, the optimization of injection and detection parameters, and gradient elution CEC.
