B. Koppen, DETERMINATION OF ETHEPHON IN PESTICIDE FORMULATIONS BY HEADSPACE GAS-CHROMATOGRAPHY, Journal of AOAC International, 80(2), 1997, pp. 289-293
A method is described for the determination of ethephon in pesticide f
ormulations. The method uses headspace gas chromatography to determine
ethylene formed from the decomposition of ethephon by the addition of
base. Method performance with respect to linearity and precision was
evaluated. Results from analyses of various pesticide formulations wer
e compared with results obtained by using the official titrimetric met
hod. The usefulness of the method was demonstrated for formulation con
trol.
