Instrument: Chemiluminescence NOx Analyzer

Instrument Short Name:
Instrument Description:

The chemiluminescence method for gas analysis of oxides of nitrogen relies on the measurement of light produced by the gas-phase titration of nitric oxide and ozone. A chemiluminescence analyzer can measure the concentration of NO/NO2/NOX.

One example is the Teledyne Model T200: https://www.teledyne-api.com/products/nitrogen-compound-instruments/t200

PI supplied instrument name: NOx analyzer
Dataset-specific description

Nitrate from shipboard extracted samples were measured using ion chromatography, where samples collected later were measured using chemiluminescence after reduction in hot acidic vanadyl sulfate solution on a NOx analyzer (Braman and Hendrix, 1989) (detection limit <0.5 uM). Nitrite was measured using the Griess-Ilosvay method followed by measuring absorption at 540nm or by chemiluminescence in a sodium iodide solution on a NOx analyzer.
