The sample, which contains suppressor and brightener, is added to the
intercept solution and measured.
Standard addition
Brightener standard solution is added once or several times to the measur-
ing solution and a measured value is recorded each time. The concentra-
tion of brightener in the sample is then calculated by means of linear
regression.

Method
Run instruction for processing a sample and performing a VA measure-
ment. A method consists of tracks that are themselves made up of com-
mands.
OCP (open-circuit potential)
In the OCP measuring mode, the circuit is opened and the potential
between the working electrode and the reference electrode is measured
for the indicated measuring duration (see Glossary, page 1046).
