ABSTRACT:
A process is provided for analyzing and detecting in an aqueous based mobile phase sample one or more N-nitroso compounds, which process includes the steps of injecting the aqueous based sample into a high pressure chromatograph to produce a liquid effluent where the nitroso compounds are resolved and separated, mixing the liquid effluent with an inert gas to produce a biphasic gas/liquid mixture, irradiating the biphasic mixture under ultraviolet irradiation to convert the nitroso compounds to nitric oxide gas, and detecting the nitric oxide produced.
