Pipette 8.0 ml of the
sample into a test tube.
Add 1 level grey micro-
spoon of Mn-1.
Add carefully 0.25 ml of
Mn-4 with pipette and
mix carefully (Foams!
Wear eye protection!).
Measuring 0.05 – 2.00 mg/l Mn 10-mm cell

Test
Add 2.0 ml of Mn-2 with
pipette and mix.
Transfer the solution into
a corresponding cell.
Select method with
AutoSelector.
Place the cell into the
cell compartment.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) ready-f
or-use
manganese standard solution Certipur
®
, Cat.No. 119789,
concentration 1000 mg/l Mn, can be used after diluting
accordingly.
Shake the tube vigor-
ously to dissolve the sol-
id substance.
Add carefully 3 drops of
Mn-3 and mix.
Reaction time:
10 minutes
Check the pH of the
sample, specified range:
pH 3 – 10.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.

Important:
When using the 50-mm cell, perform the measurement
against a separ
ately prepared blank (preparation as per
measurement sample, but with distilled water instead of
sample).
