Abstract

Chemiluminescence nitrogen detection (CLND) provides equimolar response for nitrogen-containing ions such as nitrate, nitrite, cyanide, ammonium and tetradecyltrimethylammonium. Only azide yields a lower response. Nitrite, azide and nitrate are separated on a Dionex AS11 column using 5 mM NaOH as eluent with a 3 muM (1 ng N) limit of detection. Matrices, such as 1:10 diluted seawater, do not degrade these detection limits. CLND also provides equally sensitive (Limit of detection 3 muM, 78 ppb) detection of weak acids such, as cyanide, which yield poor sensitivity with suppressed conductivity detection.
