Title: Apparatus for detection of chloromethyl methyl ether or bis-chloromethyl ether

Abstract: Apparatus for quantitatively determining the presence of chloromethyl methyl ether and/or bis-chloromethyl ether in a fluid. The above compounds are reacted in the apparatus of the invention with a reactant from the group consisting of an alkali metal salt of a lower alcohol, an alkali metal salt of phenol or an alkyl phenol, an alkali metal salt of a chlorophenol or a bromophenol, an alkali metal salt of an alkoxy phenol, an alkali metal salt of a chlorinated pyridinol, and an alkali metal salt of thiophenol, dissolved in a lower alcohol, to form derivatives which provide suitable stability, specificity and sensitivity, and then applied to a gas chromatograph utilizing a suitable detector coupled to a readout device. The apparatus is automated and controlled by timing means.
