Cell Test
Measuring 0.10 – 8.00 mg/l HCHO
range: Expression of results also possible in mmol/l.
Formaldehyde
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 f
ormaldehyde
standard solution must be prepared from Formaldehyde
solution 37%, Cat.No. 104003 (see section “Standard
solutions”).
Reaction time:
5 minutes
Add 1 level green micro-
spoon of HCHO-1K into
a reaction cell, close
with the screw cap.
Shake the cell vigorous-
ly to dissolve the solid
substance.
Add 2.0 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.
