There are several different methods available for analysing nitrite in food products. Earlier methods used cadmium reduction and colorimetric/photo spectrometry or conductivity while newer methods involve ion exchange or LC with UV detection.
EPA 300.0: Determination of inorganic anions by ion chromatography (drinking water and waste waters)
EPA 353.2: Determination of nitrogen, nitrate and nitrite with a colorimetric method - automated (water)
EPA 353.3: Determination of nitrogen, nitrate and nitrite with a colorimetric method - manual (water)
EPA 354.1: Determination of nitrogen and nitrite with spectrophotometric method (water)
