%A JP Quirino %O Copyright ? 2006 John Wiley & Sons, Ltd %T On-line sample enrichment in electrokinetic chromatography %X A challenging aspect in electrokinetic chromatography (EKe) method development is that of improving the limits of detection and quantitation, In fact, EKC and other capillary electrophoresis (CE) modes suffer from poor detection sensitivity with conventional photometric detection. This problem generally arises from the low injected sample volume and from the limited optical pathlength. %P 207-232 %B Electrokinetic Chromatography: Theory, Instrumentation and Aplications %E Ute Pyell %C Chichester, West Sussex, England %D 2006 %R 10.1002/9780470871041 %I John Wiley & Sons Ltd. %L epprod6404
