Multy
Add 1 dose of CN-1K
using the green dose-
metering cap, close with
the screw cap.
Measuring range: 10 – 350 µg/l CN
16-mm cell
Cyanide
Determination of readily liberated cyanide

Cell Test
Pipette 10 ml of the
sample into an empty
16-mm cell.
Fill approx. 10 ml of
distilled water into an
empty 16-mm cell (do
not add any reagents!),
close with the screw
cap.
(Blank cell)
Insert the cell containing
the sample into the cell
compartment. Align the
mark on the cell with
that on the photometer.
Press Test .
Reaction time:
10 minutes
Press Enter to start
the countdown.
Shake the cell vigor-
ously to dissolve the
solid substance.
Quality assurance:
To check the measurement system (test reagents, meas-
urement device, and handling) ready-for-use cyanide stan-
dard solution Certipur
®
, Cat.No. 119533, concentration
1000 mg/l CN
–
, can be used after diluting accordingly.
The measurement results are expressed in µg/l.
Heat the cell in the
thermoreactor at 120 °C
(100 °C) for 30 minutes.
Remove the cell from
the thermoreactor and
place in a test-tube
rack to cool to room
temperature.
Swirl the cell before
opening.
Add 3 drops of CN-2K,
close with the screw cap,
and mix: pretreated
sample.
Pipette 5.0 ml of the
pretreated sample
into a reaction cell,
close with the screw cap,
and dissolve the solid
substance.
Add 1 level blue micro-
spoon of CN-3K, close
with the screw cap.
Select method 1 9 0 .
Insert the blank cell into
the cell compartment.
Press Zero .
Check the pH of the
sample, specified range:
pH 4.5 – 8.0.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
