Gas chromatography injection port thermal decomposition of chlorsulfuron resulted in two
volatile decomposition products (2-amino-4-methoxy-6-methyl-1, 3, 5-triazine and 2 …

A method is described to overcome the thermalinstability of sulfonylurea herbicides and thus
enable their analysis by gas chromatography (GC). Methylationof chlorsulfuron by …

Sulfonylureas are extracted from water samples using solid-phase extraction (SPE) with Cl8-
silica/Teflon disks. Soil samples are extracted with 0.1 M sodium hydrogen carbonate, and …

Four sulfonylurea herbicides, ie chlorsulfuron, metsulfuron methyl, thiameturon methyl and
chlorimuron ethyl, were analyzed by pyrolysis-gas chromatography/mass spectrometry (Py …

A method is described for the determination of sulfonylurea herbicides by gas
chromatography (GC). Chlorimuronethyl, cinosulfuron, primisulfuron‐methyl, thifensulfuron …

An on‐line liquid chromatographic/mass spectrometric technique with direct liquid
introduction (DLI) was investigated for the analysis of chlorsulfuron, the active ingredient of …

The following selected sulfonylurea herbicides have been investigated: thifensulfuron
methyl (10), triasulfuron (11), chlorsulfuron (12), rimsulfuron (13), amidosulfuron (14), and …

A capillary column gas chromatographic method is described for determining parts-per-
trillion (ppt) levels of chlorsulfuron in agricultural runoff water. The water sample is acidified …

MATERIALS AND METHODS Chemicals. Analytical standards (> 99% pure) for nicosulf-
uron, rimriduron, and the two metabolites were synthesized at the Experimental Station (Du …

The measurement of the sulfonyl urea herbicides, chlorsulfuron and metsulfuron‐methyl as
pentafluorobenzyl derivatives has been investigated and the kinetics of reaction optimised …
