Determination of DDVP in DDVP-Dipterex Formulations by Gas Chromatography
Keyword(s):
Abstract In the analyses of commercial fly-bait samples for DDVP (0,0-dimethyI-2,2-dichloro vinyl phosphate), containing Dipterex (0,0-dimethyl-2,2,2-trichloro - 1 - hydroxyethyl phosphonate) as a guaranteed ingredient, interferences were observed at 9.9– 10.4/t with the current spectrophotometric methods. These samples were analyzed by an electron capture gas chromatographic method, and the results showed no interference from Dipterex or other substances. A selected group of samples was analyzed by gas chromatography and spectrophotometry, and the results were compared.
