Water quality. Determination of nitrite nitrogen and nitrate nitrogen and the sum of both by flow analysis (CFA and FIA) and spectrometric detection Ingestion-build-221493 This British Standard is applicable1 Scope This International Standard specifies a method for the determination of nitrite(N) (see note 2), nitrate(N) or the sum of both [nitrite nitrate(N)], in various types of waters (such as ground, drinking, surface, and waste waters) in mass concentrations ranging from 0,01 mg l to 1 mg l for nitrite(N) and from 0,2 mg l to 20 mg l for nitrite nitrate(N), both in the undiluted sample. The range of application can be changed by varying the
