Determination of Linuron and Its Metabolites by GLC and HPLC

Abstract
Methods for analysing the urea herbicide linuron and its metabolites either by GLC after ethylation or directly by HPLC, using normal and reverse phase respectively, have been developed and a comparison has been made between the two methods, the former using electron capture and flame-ionization detection and the latter using an UV-adsorption detection method. Mass spectra of the compounds and their ethyl derivatives, which were used to verify the identification, are also presented.
