原始语种摘要: Abstract(#br)Normal and reversed electroosmotic flow (EOF) capillary electrophoresis (CE) has been studied for the analysis of eight triazine herbicides. Reversed EOF CE, dynamically modified with cetyltrimethylammonium bromide (CTAB), provided better separation than normal CE. All eight triazines were baseline resolved with the use of 50 m M ammonium acetate and 0.7 m M CTAB as the running buffer. The method of sheath liquid was used in the on-line coupling of CE with electrospray mass spectrometry. The composition of sheath liquid was found to be critical in the coupling of reversed EOF CE with MS. The resolution obtained in CE–UV can be preserved in CE–MS if the composition of the sheath liquid is similar to the running buffer.
