The NO electrode and membrane inlet mass spectrometry (MIMS) have the advantage of being sensitive, direct, and real time detectors of NO in aqueous solution. They do not require reacting NO with labels or purging of NO with in inert gas. We show that the NO electrode and MIMS are comparable in sensitivity detecting NO concentrations to 0.5 nM in aqueous solution, and both give identical results in a biological measurement, the reactions of deoxyhemoglobin with nitrite.
