Water quality - Determination of nitrite nitrogen and nitrate nitrogen and the sum of both by flow analysis (CFA and FIA) and spectrometric detection (ISO 13395:1996)

According to the methods specified in this document nitrite and nitrate by be determined in large sample series and a high analysis frequency. The method includes an automatic dosage.

Wasserbeschaffenheit - Bestimmung von Nitritstickstoff, Nitratstickstoff und der Summe von beiden mit der Fließanalytik (CFA und FIA) und spektrometrischer Detektion (ISO 13395:1996)

Qualité de l'eau - Détermination de l'azote nitreux et de l'azote nitrique et de la somme des deux par analyse en flux (CFA et FIA) et détection spectrométrique (ISO 13395:1996)

La présente Norme internationale prescrit une méthode pour la détermination de l'azote nitreux, de l'azote nitrique ou de la somme des deux dans différentes eaux (par exemple eau souterraine, eau potable, eau de surface et eaux usées), en concentrations en masse dans les gammes allant de 0,01 mg/l à 1 mg/l pour l'azote nitreux et de 0,2 mg/l à 20 mg/l pour la somme des azotes nitreux et nitrique, dans les deux cas pour des échantillons non dilués. Le domaine d'application peut être modifié en faisant varier les conditions de travail.
NOTES 1  L'eau de mer peut être analysée en modifiant la sensibilité et en adaptant la solution vecteur et les solutions d'étalonnage à la teneur en sel de l'échantillon. 2  Les termes suivants sont utilisés dans la présente Norme internationale:
nitrite(N): azote nitreux (concentration en masse)
nitrate(N): azote nitrique (concentration en masse)
nitrite/nitrate(N): somme de l'azote nitreux et de l'azote nitrique (concentration en masse)

Kakovost vode - Določevanje nitritnega in nitratnega dušika in vsota obeh s pretočno analizo (CFA in FIA) in spektrofotometrijsko detekcijo (ISO 13395:1996)

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 13395 was prepared by Technical Committee
lSO/TC 147, Water quality, Subcommittee SC 2, Physical, chemical,
biochemical methods.
Annexes A, B, C and D of this International Standard are for information
only.

llntroduction
Methods using flow analysis enable wet chemistry procedures to be
automatized and are particularly suitable for the processing of many
analytes in water in large series of samples at a high analysis frequency
(up to 100 s amples per hour).
A differentiation is made between flow injection analysis (FIA) [I][*] and
continuous flow analysis (CFA) [31. Both methods share the feature of an
automatic dosage of the sample into a flow system (manifold) where the
analytes in the sample will react with the reagent solutions on their way
through the manifold. The sample preparation may be integrated in the
manifold. The reaction product is measured in a flow detector (e.g. flow
photometer).
