Pipette 4.5 ml of
HCHO-1 into an empty
round cell (Empty cells,
Cat.No. 114724).
Measuring 0.10 – 8.00 mg/l HCHO 10-mm cell
range: 0.05 – 4.00 mg/l HCHO 20-mm cell
0.02 – 1.50 mg/l HCHO 50-mm cell
Expression of results also possible in mmol/l.
Formaldehyde
114678
Test
Transfer the solution into
a corresponding rectan-
gular cell.
Select method with
AutoSelector.
Place the cell into the
cell compartment.
Reaction time:
5 minutes
Add 1 level green micro-
spoon of HCHO-2,
close the cell with the
screw cap.
Shake the cell vigorous-
ly to dissolve the solid
substance.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) a f
ormaldehyde
standard solution must be prepared from Formaldehyde
solution 37%, Cat.No. 104003 (see section “Standard
solutions”).
Add 3.0 ml of the
sample with pipette,
close the cell with the
screw cap, and mix.
Caution, cell
becomes hot!
Check the pH of the
sample, specified range:
pH 0 – 13.
Note:
Empty cells with screw caps, Cat.No. 114724 are
recommended for the preparation.
These cells can be
sealed with the screw caps, thus enabling a hazard-free
mixing of the sample.
