Equipment required:
Wash bottle with distilled or deionized water.
Several clean beakers.
1 mL, 10 mL and 50 mL pipettes (a 50 ml graduated
cylinder can also be used).
Technical notes:
All standard solutions should be prepared fresh.
The standard solutions should be at the same
temperature as the sample.
Use ISA in all solutions (also recommended for the
measured sample).
Note: ISA is added to all solutions to ensure the
samples and standard solutions have the same ionic
strength; the ratio is 1:50.
