Calculation procedure 8 (C/S/SbRb)
Method at which the difference of reagent blank A
RB
and blank of reagent blank A
RBB
regarding the amount is
subtracted of the difference of sample value A
S
and sample blank A
SB
regarding the amount and this difference
is multiplied with a factor F which is determined by measuring of a standard solution with known concentration
C
ST
and under consideration of standard blank A
STB
and the difference of reagent blank A
RB
and blank of
reagent blank A
RBB
The sample blank A
SB
is measured before every test. The reagent blank A
RB
is entered or measured once.
