Water quality. Determination of ammonium nitrogen. Method by flow analysis (CFA and FIA) and spectrometric detection Ingestion-build-189776 4 Size designation and dimensions1 Scope This International Standard specifies methods suitable for the determination of ammonium nitrogen in various types of waters (such as ground, drinking, surface, and waste waters) in mass concentrations ranging from 0,1 mg l to 10 mg l (in the undiluted sample), applying either FIA (Clause 3) or CFA (Clause 4). In particular cases, the range of application may be adapted by varying the operating conditions.
