To check the measurement system (test reagents,
measurement device, and handling) w
e recommended
to use Spectroquant
®
CombiCheck 40, Cat.No. 114692.
Ready-for-use aluminium standard solution Certipur
®
,
Cat.No. 119770,
concentration 1000 mg/l Al, can also
be used after diluting accordingly.
To check for sample-dependent effects the use of addition
solutions (e.g. in CombiCheck 40) is highly recommended.
Pipette 5.0 ml of the
sample into a test tube.
Add 1 level blue
microspoon of Al-1
to the test tube and
dissolve the solid
substance.
Add 1.2 ml of Al-2
with pipette and mix.
Measuring 0.10 – 1.20 mg/l Al 10-mm cell
range: 0.05 – 0.60 mg/l Al 20-mm cell

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.
