We describe an ion chromatography system using a Dionex AS4A‐SC column with carbonate–bicarbonate buffer (1.8–1.7 m m ) as eluent for the evaluation of urinary NO 2 − and NO 3 − . This chromatographic system gives an accurate measurement of NO 2 − and NO 3 − in the urine as an index of NO production in vivo , making also possible to evaluate their relative proportion and providing useful tools to investigate the NO system. © 1998 John Wiley & Sons, Ltd.
