In an ISE standard addition method with programmed volumes, the
user enters the volume of each addition being performed.
To avoid modifying the ionic strength of the solution by dilution effect,
it is recommended to add small amounts of standard. The addition
cumulate volumes should not exceed 10% of the sample test quantity.
Example:
5 additions programmed with a sample amount of 1 ml.
Enter a volume for one addition equal to or less than 20 µl and use a
1 ml burette to perform the 5 additions.
