photoLab®Series

The following methods are programmed into the photometer and measurements can be made without any
further adjustments. Method selection is achieved through a barcode on the cell (for cell tests) or through a
barcode on the AutoSelector (for reagent tests). The method number listed in column 1 is for manual selection.
The total range relates to the cited test in column 2 and, in the reagent tests, covers all possible path length
(cells from 10 to 50 mm).

range: 0.26 – 10.30 mg/l NH4
0.20 – 8.00 mg/l NH3-N
0.24 – 9.73 mg/l NH3
Expression of results also possible in mmol/l.
Pipette 1.0 ml of the
sample into a reaction
cell
, close with the screw
cap,
and mix.
Add 1 dose of NH4-1K
using the blue dose-
metering cap, close the
cell with the screw cap.
Shake the cell vigorous-
ly to dissolve the solid
substance.
Reaction time:
15 minutes
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) we recommended
to use CombiCheck 10, Cat.No. 250482.
Ready-for-use ammonium standard solution, Cat.No.
250461,
concentration 1000 mg/l NH4
+, can also be used
after diluting accordingly.
To check for sample-dependent effects the use of addition
solutions (e.g. in CombiCheck 10) is highly recommended.
Important:
Very high ammonium concentrations in the sample
produce turquoise-colored solutions (measurement solu-
tion should be yellow-green to green) and false-low read-
ings are yielded. In such cases the sample must be di-
luted (plausibility check).
Check the pH of the
sample, specified range
:
pH 4 – 13.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
