III. System layout and functions
3.1.1 Measuring cell
Standard delivery of the Mütek™ PCD-06 includes a
precision measuring cell and a displacement piston. Fit-
ted in the measuring cell are two platinum electrodes for
identifying the streaming potential.

3.1.2 pH set (optional)
The Mütek™ PCD-06 Smart identifies not only the
charge level but also the pH of a sample.
In combination with a Travel Titrator module or an exter-
nal Titrator, the instrument can determine the isoelectric
point of a sample via the pH electrode.
Install the pH electrode in the measuring cell on the wall
opposite the titrant tubes, that is at a maximum distance
from the tube tips.

Designations
1 Electrode cable with A2 connector
2 Plexiglass shaft
3 Clip
4 Ceramic diaphragm
5 Electrode cap
The pH electrode must immerse in the sample solution.
Therefore it is necessary to use an increased sample
volume of 30 ml for isoelectric point measurements. Use
more sample material and do not dilute the sample with
water!
When just one pH value has to be measured (no pH
curve or IEP measurement) the pH of the 10 ml sample
can be measured outside before filling into the measu-
ring cell.
