Hidalgo C, Sancho JV, Lopez FJ, Hernandez F: Automated determination of phenylcarbamate herbicides in environmental waters by on-line trace enrichment and reversed-phase liquid chromatography-diode array detection. J Chromatogr A. 1998 Oct 9;823(1-2):121-8.
A fully automated liquid chromatographic method using on-line trace-enrichment, gradient elution and diode array detection is described for the trace-level determination of several phenylcarbamate herbicides, such as carbetamide, propham, desmedipham, phenmedipham, chlorbufam and chlorpropham, in environmental water samples.
Using the C18 pre-column, up to 50 ml of water sample could be percolated without peak broadening of any compound. |
