Measurement
After Measurement
(1) Put 50 mL of sample solution (250 mg/
L) in a 100 mL beaker.
(2) Add 1 mL of ISA.
(3) Stir the solution slowly with a magnetic
stirrer.
2
Rinse the electrode with pure water.
3
Wipe off the moisture.
Wipe off the moisture using soft and clean lint-free paper or cloth.
It is best to control the stirring
speed so that the stir bar will
rotate 3 or 4 turns per second.
If swirling occurs on the
surface, the stirring speed is
too fast. Reduce the speed to
a level where swirling does not
occur.
About the amount of ISA
(
In the case using different volume from the example, note
that the volume ratio shall be the sample solution: the ISA =
50:1.
