Organochlorine pesticides were tested in order to establish optimal conditions for rapid detection in dried leafy matrices, using DRS software. In tests we have used dried Trifolium pratense herba fortified with OC pesticide mix, processed with modified QuEChERS method. Instrumental analysis was carried out complying Agilent "key" condition, column of 15 m, in which case the retention time for chlorpyrifos-methyl was 8,296 min. DRS allows linear calibration in the concentrations range 0,05-1 mg/kg for most of pesticides; for concentrations ≤, of 0.05 mg / kg is needed most advanced purification method or acquisition in SIM mode.
