Preproduction Test Report for the Determination of Hydrocarbon Contaminants in Trichlorethylene in Concentrations of Approximately 10 Parts Per Million, Spec. No. AR-270-1-11A

Abstract

The investigations described in this report were carried out to develop a method of determining low concentrations of greases and oils in commercial trichlorethylene which would be more economical than the procedure described in AR-270-1-11A. Analysis of the samples by gas chromatography was ruled out because of the lack of volatility of the hydrocarbon contaminants. Infra-red techniques applied in this test were incapable of accurately determining hydrocarbons in trichlorethylene in concentrations below 50 ppm. The application of nuclear magnetic resonance techniques to the problem was found to be impractical because commercial trichloroethylene has an NMR spectra whose secondary peaks coincide with those due to hydrocarbons.
