Assessment of the measurement value relative to the ideal range defined by you.
Measurement value for this parameter is outside the value range of this method.
Note(s)
-> If you intend to use last ZERO, please ignore steps where you are
asked to prepare a ZERO vial.
-> (*) Conversion of the measurement result to NH , NH .
-> This test can be used for water, wastewater and seawater.
-> Remove powder from vial edges, lid and tube threads after adding powder
(PL Phosphorus 2)
-> Use volumetric pipettes to dose exactly 2ml of the Acid LR/HR reagent
-> Reagents might not dissolve entirely
-> Incubation time shall NOT exceed 30 minutes!
-> Step 20 to be performed by turning vial upside down and back, waiting for
the solution to entirely flow down. Inverse 10 times
-> Zero vial can be stored and used for max. 7 days if stored in the dark
-> Sample needs to be diluted and measurement needs to be repeated if large
quantities of nitrogen free, organic compounds are present, as they may
interfere and reduce the effectiveness of the digestion
-> Bromide >60 mg/l and Chloride >1000 mg/l interfer and change result with
+10%
