INTERFACING A ROBOTIC STATION WITH A GAS CHROMATOGRAPH FOR THE FULL AUTOMATION OF THE DETERMINATION OF ORGANOCHLORINE PESTICIDES IN VEGETABLES

摘要

A fully automated method for the determination of organochlorine pesticides in vegetables is proposed. The overall system acts as an "analytical black box" because a robotic station performs the preliminary operations, from weighing to capping the leached analytes and location in an autosampler of an automated gas chromatograph with electron capture detection. The method has been applied to the determination of lindane, heptachlor, captan, chlordane and metoxychlor in tea, marjoram, cinnamon, pennyroyal, and mint with good results in most cases. A gas chromatograph has been interfaced to a robotic station for the determination of pesticides in vegetables.
