Title: (EN) METHODS AND APPARATUS FOR IMPROVING THE SENSITIVITY OF CAPILLARY ZONE ELECTROPHORESIS
Abstract: front page image
(EN) The present invention relates to novel methods and apparatus for improving the sensitivity of capillary zone electrophoresis (CZE). The invention particularly concerns devices comprising a channel that contains an in-line sol-gel column to concentrate samples being subjected to capillary zone electrophoresis, and the use of such devices to enhance the sensitivity of capillary zone electrophoresis. ┬ęKIPO&WIPO 2008
