Abstract

Thirteen compounds are investigated using a commercially available CE system and capillary columns packed with 3-μm porous octadecylbonded silica. The detector response is very linear from 1-100 ppm with a correlation coefficient r 2 of 1-0.990 for each compound. This paper is believed to be the first application using CEC for the determination of sulfonyl urea herbicides and the first reported use of hydrodynamic injection in CEC with packed columns and a commercial CE instrument.
