Connecting from the Nano to the Titrator
The connections used on the titrator are of the "Luer lock" variety. The diagram
below shows how to connect the tubing, from the cells mentioned above, to the
tubing connection bracket. Similar connections are used throughout the unit; the
connections may differ slightly, but the connection principle is the same.

If a filter is used, attach this to the sample out (To Zetasizer) connection in the
same manner as the direct tubing, then connect the tubing to it.
Preparation for measurement
Some setup procedures will have to be performed daily, while others will only have
to be performed at much longer intervals.
Typically, setup before performing a measurement will involve one or more of the
following operations:

Filling the titrant containers. Only required when the containers are nearly
empty.

Priming the titrant syringe pumps and tubes . Usually done at the begin-
ning of the day or at the start of a new measurement session.

Calibrating the pH probe. Usually performed before each titration session.

Preparing the measurement sample . Performed before each titration ses-
sion.

Filling of the measurement cell. Performed before each titration session.
To perform these operations the titrator manual control dialogue will be required.
Where necessary refer to the Software and control chapter.
