Pipette 10 ml of the
sample into a reaction
cell, close with the screw
cap, and mix.
Add 1 level grey micro-
spoon of Ph-1K, close
the cell with the screw
cap.
Reaction time:
1 minute

Cell Test
Measuring 0.10 – 2.50 mg/l phenol
range: Expression of results also possible in mmol/l.
Phenol
Shake the cell vigorous-
ly to dissolve the solid
substance.
Add 1 level green micro-
spoon
of Ph-2K, close
the cell with the screw
cap.
Shake the cell vigorous-
ly to dissolve the solid
substance.
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) a phenol standard
solution must be prepared from Phenol GR, Cat.No.
100206
(see section “Standard solutions”).
Check the pH of the
sample, specified range
:
pH 2 – 11.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
Important:
Very high phenol concentrations in the sample result in
a weakening of the color and f
alse-low readings are
yielded. In such cases the sample must be diluted
(plausibility check).
