A multi-residue analytical method based on solid-phase extraction enrichment combined with capillary electrophoresis (CE), using micellar electrokinetic capillary chromatography, was developed to isolate, recover and quantitate three sulfonylurea herbicides (chlorsulfuron, chlorimuron and metasulfuron) from soil samples.

Abstract
A multi-residue analytical method based on solid-phase extraction enrichment combined with capillary electrophoresis (CE), using micellar electrokinetic capillary chromatography, was developed to isolate, recover and quantitate three sulfonylurea herbicides (chlorsulfuron, chlorimuron and metasulfuron) from soil samples. Optimization for CE separation was achieved using an overlapping resolution map scheme. The recovery of each herbicide was >80% and the limit of detection was 10 ppb. The capability of CE in providing quantitative analysis of sulfonylureas in soil samples at the ppb level has been demonstrated. © 1995.File in questo prodotto:
