This part of ISO 10304 specifies a method for the chloride, nitrite, determination of fluoride, orthophosphate, bromide, nitrate and sulfate in water with low contamination (e.g. drinking water, rain water, ground water and surface water) in the following ranges:
Fluoride (F):
Chloride (CI):
Nitrite (NO₂):
Orthophosphate (PO4):
Bromide (Br):
Nitrate (NO3):
Sulfate (SO4):
0,01 mg/l to 10 mg/l
0,1 mg/l to 50 mg/l
0,05 mg/l to 20 mg/l
0,1 mg/l to 20 mg/l
0,05 mg/l to 20 mg/l
0,1 mg/l to 50 mg/l
0,1 mg/l to 100 mg/l
NOTE 1 Anion symbols are used without charges throughout the text.
In certain cases, the range of application may be changed by variations in the working conditions (e.g. sample volume, dilution, separating columns, pre-concentration techniques, sensitivity ranges of detectors, etc.).
