Check the pH of the
sample, specified range
:
pH 3 – 8.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
Pipette 5.0 ml of the
sample into a reaction
cell, do not mix!
Add 0.50 ml of T-1K with
pipette and close with
the screw cap.
Reaction time:
5 minutes
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.

Cell Test
Surfactants (cationic)
Measuring 0.05 – 1.50 mg/l surfactants (cationic)
range: (calculated as N-cetyl-N,N,N-trimethylammonium bromide)
Swirl the cell for
30 seconds.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) a surf
actants
standard solution must be prepared from N-cetyl-N,N,N-
trimethylammonium bromide, Cat.No. 102342 (see section
