Abstract Methyl parathion in technical material, 4 lb/gal. emulsifiable concentrate, and 6 lb toxaphene-3 lb methyl parathion/gal. emulsifiable concentrate was chromatographed on microparticulate silica with 40% water-saturated chloroform mobile phase and 254 nm ultraviolet detection. Ten collaborators reported results on 3 matched pairs of samples by peak height measurements with acetophenone as internal standard. The mean of the coefficients of variation for the 6 samples was 1.71%. Results for 4 of the samples were compared with gas-liquid chromatographic results on the same samples. No difference in the means by the 2 methods was noted at the 95% confidence level. The method has been adopted as official first action.
