NOTE
You can also use the parameter Fixed sample size if you would like to
establish a default for the sample size.
Example: For a particular determination, you require 10 mL of sample.
Now and again, however, you have too little sample available and you
must perform the determination with 5 mL, for instance. In this case,
proceed as follows:
1. Activate the parameter Fixed sample size.
2. Define the value and unit for the sample size, in the above exam-
ple, for instance, [10 mL].
3. Deactivate the parameter Fixed sample size again.
4. Save the method.
⇨ Each time you load this method, 10 mL is entered as the sample size,
but in the example mentioned you can enter the lesser quantity of 5
mL.
