Assignment
on | off (Default value: on)
Shows the assignment of a result to one of the 25 possible result columns.
Formula
on | off (Default value: on)
Shows the formula with which the concentration of a substance in a sam-
ple was calculated.
Variables
on | off (Default value: off)
Shows the variables used in the formula.
NOTE
Variables that have not been created in the run are not displayed and
lead to invalid results.
Calculation of the concentration of a substance:
NOTE
The calculation does not apply to Dilution Titration.
Concentration(sample) = concentration(measuring cell) * (cell volume /
sample amount) * (dilution volume / analysis volume)
Concentration(sample) Concentration of the analyte in
the sample
Variable = CONC
Concentration(measuring cell) Concentration of the analyte in
the measuring cell at the moment
of sample measurement
Variable = CONCM
Cell volume Sum of the volumes of all solu-
tions added to the measuring cell
until the measurement of the
sample.
Variable = VAR{1}.VTOT
