Analate Subtraction

The analate subtraction method is particularly useful in the event that

there is no ion specific electrode available to directly measure the

concentration of the ion of interest. This method employs the addition

of a sample of the ion of interest to a standard containing a different

ion of known concentration. The ion of interest will quantitatively react

with the ion in the standard, creating a complex and removing the ion

from the standard solution. The ion specific electrode is specific for

the ion in the standard solution and not for the ion of interest. The

difference in mV potential is used to calculate the concentration of the

ion of interest based upon this quantitative reaction.

8.3 Select Measurement Units

This screen allows you to select the units in which the meter will

report the concentration of the ion of interest. The current units are

displayed on the screen.
