    摘要: A method of determining the content of polar-substituted alkyl nitrosoamines in a sample at levels as low as 20 nanograms in the presence of interfering substances such as nitrites and the like. After chromatographic separation, the nitrosoamine is reacted with reagent comprising hydrogen bromide, sulfanilamide, hydrochloric acid, surfactant and N-(1-naphthyl)ethylenediamine to give a colored product.
