Chemiluminescence signals of plasma nitrite: Peak 1, 100 μl plasma was injected into 8 ml of 87.5% glacial acetic acid reagent. This peak was completely suppressed in the presence of 200mM sulfanilamide (sulfa) in 87.5% glacial acetic acid. Peak 2, 100 μl plasma was injected into7 ml glacial acetic acid and 1 ml (0.5M) ascorbic acid. This peak was almost completely suppressed in the presence of 200 mM sulfa in 87.5% glacial acetic acid and 1 ml (0.5M) ascorbic acid.
