Controlling An Szp Measurement Via An Sop - Malvern Zetasizer Nano Series Accessories Manual

Chapter 3
Controlling an SZP measurement via an
SOP
Once the cell has been inserted into the Zetasizer and zeroed, a measurement can
be made. This is done using an SOP, or a manual measurement in the usual
manner.
An SOP can be configured to control all settings for the accessories automatically.
A surface zeta potential (SZP) measurement follows the same SOP format as
performed when doing a normal zeta potential measurement, with a few
exceptions. When a SZP measurement is chosen two extra dialogues - SZP
measurement and Tracer measurement - will be included in the SOP
selections.
The SOP Editor and setup is described in full in the Zetasizer Nano user
manual. Most of the SOP sections are common to Measurement types, and these
are described in the above manual. The other SOP sections are specific to the SZP
cell being used; these are described below. Also note that some of the other
dialogue pages will alter slightly to accommodate extra parameters necessary to
perform the SZP measurement.

Select a surface zeta potential measurement type then complete the SOP
creation as required.
Tracer Material
Please refer to the Sample - Material description in the zeta potential SOPs
section of the main user manual.

To create a new SOP, select File-New SOP. This will open up the SOP Edi-
tor. The SOP Editor consists of several dialogues that can be stepped through
by using the Next arrow button.
(To edit an existing SOP, choose Open-SOP instead.)
Complete the SOP Editor as described in the Zetasizer Nano user manual.
Once the SOP has been created, press Finish and save the new SOP.
