Volatile Organic Acids
Quality assurance:
To check the measurement system (test reagents, meas-
urement device, and handling) a standard solution must
be prepared from sodium acetate anhydrous, Cat.No.
106268 (see section “Standard solutions”).
Add to each cell 1.0 ml of
OA-2K with pipette.
Heat both cells in the
thermoreactor at 100 °C
for 15 minutes. Then cool
to room temperature
under running water.
Pipette 0.50 ml each of
OA-1K into two reaction
cells.
Add to one cell 0.50 ml
of the sample with pi-
pette, close with the
screw cap, and mix.
Add to each cell 1.0 ml
of OA-3K with pipette,
close with the screw cap,
and mix.
Add to each cell 1.0 ml
of OA-4K with pipette,
close with the screw cap,
and mix.
Add to the second cell
0.50 ml of distilled water
with pipette, close with
the screw cap, and mix.
(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 .
Insert the blank cell into
the cell compartment.
Align the mark on the
cell with that on the pho-
tometer. Press Zero .
Check the pH of the
sample, specified range:
pH 2 – 12.
Select method 5 3 1 .
Reaction time:
1 minute
