Calculation procedure 6 (C/S/Rb)
Method at which the difference of sample value A
S
and reagent blank A
RB
is multiplied with a factor F which is
determined by measuring of a standard solution with known concentration C
ST
and under consideration of
reagent blank A
RB
.
The reagent blank A
RB
is entered or measured once.
