Calculation procedure 7 (C/S/Sb)
Method at which the difference of sample value A
S
and sample blank A
SB
regarding the amount 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.
The sample blank A
SB
is measured before every test.
Calculation procedure ....................................................... CP 7
Characteristic ............................................................ C / S / Sb
Method ............................................... End Point with Standard
Calculation formula ....................................... C = F
