Analytical separations in open-tubular capillary electrochromatography
(2003)This review represents a summary of recent progress in open-tubular capillary electro-chromatography (OT-CEC) for chiral and achiral separations. The OT-CEC approach is an alternative to packed-CEC that could eliminate the ...
