Analytical Methodology for Herbicide Orange. Volume II:Determination of Origin of USAF Stocks.

摘要

A method was developed for gas-chromatographic characterization of chlorophenoxy herbicide formulations;with this method the original manufacturer of the herbicide could be determined. Using a temperature-programmed flame-ionization gas chromatograph, a gas chromatogram was obtained for each of several herbicide specimens. It was found that the amount and type of impurities determined gas chromatographically are characteristic of the original manufacturer of the material. In addition,this simple analytical method was used to determine the homogeneity of the USAF herbicide stocks. These data were used to prepare Environmental Impact Statements for the Environmental Protection Agency.
