Abstract
Disclosed is a liquid chromatography process for the quantitative determination of nitro-amines and nitro-aromatics in liquid samples, which comprises directly injecting a liquid sample containing these compounds onto a liquid chromatography column, separating the compounds on the column by elution, and then monitoring the ultra-violet absorbance of the resulting eluant. The instant process finds particular application in the quantitative detection of munitions, such as HMX, RDX, TNT, and their degradation products, in aqueous effluent streams.
