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,Ol 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 operating conditions.
NOTES
1 Seawater may be analysed with changes in respect to
sensitivity and adaptation of the carrier solution and calibration
solutions to the salinity of the samples.
2 The following concise terms are used in the text of this
International Standard:
nitrite(N):
nitrate(N):
nitrite,/nitrate(N):
(mass concentration of) nitrite,
expressed as nitrogen
(mass concentration of) nitrate,
expressed as nitrogen
(mass concentration of) the sum
of nitrite(N) and nitrate(N)
