accessory preparation
Introduction
This chapter describes the actions necessary for preparing the titrator and degasser
accessories ready for measurements to be performed. It covers:

Connecting the MPT-2 Titrator and Vacuum degasser to the Zetasizer Nano.

Preparing the titrant and sample tubing and containers.

Calibration of the pH probe.
Connecting the titrator and degasser
This section gives instructions on how to connect the accessories to the Zetasizer
Nano optical unit. Initially the accessory will have been commissioned by a Mal-
vern Instruments representative.
Note that when the accessory is to be moved short distances, then a sample con-
tainer containing water should be attached to the dispersion head to prevent the pH
probe from drying out. If the accessory is to be moved greater distances then the
pH probe should be removed and its protective cover attached to prevent the probe
from drying out.
Follow the installation instructions for the Zetasizer Nano as detailed in the Zeta-
sizer Nano user manual, then connect the Titrator as described below.
