[Liquid chromatographic parameters of groups of herbicidal active substances. I. Urea herbicides].
Because of the polarity of herbicidal urea derivatives, liquid chromatography is the most suitable method for their determination. The separation of a number of active substances is described. A versatile applicable ternary solvent mixture is used as the mobile phase. Several columns are tested for their separation performances and their capability to retain active substances and some known degradation products. To fully utilize the sensitivity of the photometric detector the UV spectra of the tested compounds are determined.
