The variation with concentration of nitrite of the generation of NO measured by membrane inlet mass spectrometry. Sodium nitrite was added at time zero to achieve the final concentrations indicated. Solutions also contained 14 µM deoxy-Hb(FeII). Solution conditions were as described in Fig. 3 except pH was 6.7 at 25° C and 2 mM diethylenetriaminepentaacetate was used as chelator.
