Cell Test
Measuring 50 – 3000 mg/l volatile organic acid
range: (calculated as acetic acid)
Volatile Organic Acids
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.
Reaction time:
3 minutes
Add 5.0 ml of OA-5 with
pipette, close the cell
with the screw cap, and
shake vigorously.
Heat the cell in the ther-
moreactor at 100 °C for
10 minutes. Then cool to
room temperature under
running water.
Add 5 drops of OA-3.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) a standard solution
m
ust be prepared from sodium acetate anhydrous,
Cat.No. 106268 (see section “Standard solutions”).
Check the pH of the
sample, specified range
:
pH 2– 12.
