Sample subtraction

In the

Sample subtraction

procedure, a known amount of test sample

is added to the standard solution.

The ion concentration in the sample is calculated from the change in
potential.

The sample subtraction is one method for the indirect determination of
ions. It is used for the determination of ions for which no direct determi-
nation is possible.

Calibration

Measuring

1

Check the currently displayed ion.
If the ion to be measured is displayed incorrectly:
Select the ion type in the menu,

2

In the

menu, select the method,

Sample subtraction

.

3

Carry out a two-point calibration according to the user guid-
ance (see page 106).
As soon as a stable value is achieved for the second standard
calibration solution, the slope (mV) and evaluation (Error, +++)
of the electrode after calibration is displayed.
The infotext,
