Abstract
Abstract The operating parameters for electron capture and flame ionization detectors are discussed, and the effects of varying each are described. Investigation of the detection of organophosphorus pesticides by a hydrogen flame burning in an atmosphere of alkali metal salts has resulted in increased sensitivity and complete specificity. With the use of potassium salts, sensitivity for phosphorus compounds equals that of the electron capture detector for chlorinated hydrocarbon pesticides. A detection system using both detectors to obtain a dual analysis simultaneously is described. Specificity is achieved with certain halogen salts (KCl, KBr, RbCl) which suppress the minor enhanced response by the modified flame detector to organohalogen compounds.
