5.3 Measurement Using Standard Addition Method
74 HORIBA
5.3.3 Measuring Ion Concentration in Sample Addition 1 Mode
This mode is used to obtain the ion concen-
tration of the target ion species by adding a
small amount of the sample to the standard
solution for the ion species to measure once,
thus increasing the ion concentration of the
target component, and then measuring the
change in electric potential which occurs at
that time.
