Chromatographic Separation of Pesticides from Various Chemical Classes

Features of chromatographic separation of pesticides from various chemical classes by the reversed-phase (RP) high-performance liquid chromatography (HPLC) method under isocratic mode of elution are shown. The most complete separation of the test substances is achieved using a lead electrolyte containing acetonitrile and 0.01 M ortho-phosphoric acid in a ratio of 3:2 (v/v), a flow rate of 0.5 mL min-1 , a column thermostat temperature of 40u00b0C, a detection wavelength of 230 nm, and the volume of the injected sample of 10 u03bcL. The separation time is 35 min. Under these conditions, the values of the chromatographic parameters, in particular, peak resolution (Rs), capacitance factor (k'), asymmetry factor (As), and selectivity coefficient (u03b1), have optimal limits.
