2.3.3.6 User-defined result variables
Dialog window: Formula editor ▶ Variables
User-defined result variables are generated for the user-defined results
defined by the user in the method. A basic distinction is made between
single results and multiple results.
A single result is an individual numerical value which is calculated
according to a specified formula.
In the case of a multiple result, a formula is specified with which a result
is calculated in the same way for each substance.
Syntax
Single result:
￭ 'RS.Result name'
Multiple result:
￭ 'RS.Command name.ASU.Result name', where ASU stands for "all
substances" and represents all substances as a wildcard.
￭ 'RS.Command name.Substance name.Result name', where the
Substance name represents precisely one specific substance.
2.3.3.7 Determination variables
Dialog window: Formula editor ▶ Variables
Determination variables are general variables that are generated in the
method run. They are not assigned to individual commands. The Varia-
bles field of the formula editor lists the Determination variables which
are available for the current method, sorted according to name.
Syntax
'DV.Variable identification'
Examples: 'DV.DUR', 'DV.STT'
Determination variables can be selected directly in the formula editor
under Variables
▶ Determination variables so as to avoid syntax
errors.
