Transfer the solution into
a corresponding cell.
Select method with
AutoSelector.
Place the cell into the
cell compartment.
Important:
To measure in the 50-mm cell, the sample volume and
the volume of the reagents hav
e to be doubled for each.
Alternatively, the semi-microcell, Cat.No. 173502, can be
used.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) a h
ydrazine standard
solution must be prepared from Hydrazinium sulfate GR,
Cat.No. 104603 (see section “Standard solutions”).
Check the pH of the
sample, specified range:
pH 2 – 10.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
