Cell Test
Measuring 50 – 3000 mg/l volatile organic acid (calculated as acetic acid)
range: 71 – 4401 mg/l volatile organic acid (calculated as butyric acid)
Volatile Organic Acids
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.
Add 1.0 ml of OA-4 with
pipette, close the cell
with the screw cap, and
shake vigorously.
Heat the cell in the ther-
moreactor at 100 °C for
15 minutes. Then cool to
room temperature under
running water.
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.
