Prepare the second solution for calibration.
(1) Put 50 mL of 1000 mg/L standard solution into a 100 mL beaker.
(2) Add 1 mL of ISA.
(3) Stir the solution slowly with a magnetic stirrer.
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.
Additive amount of ISA
(
In the case using different volume from the example, note
that the volume ratio shall be the standard solution: the ISA
= 50:1.
