
Name .
This is a title for the titrant.

Concentration .
Specifies the concentration of the titrant, this is usually between 1.0M and
0.01M. The concentration chosen will affect the precision of titration measure-
ment.

Results
The results are shown in graphical form.
The graph shows a plot of the titration performed, with each titration measurement
point indicated on the graph. The
Total injected Volume (ml) is indicated at the
top of the graph. This is the amount of titrant injected into the sample during the
course of the measurement.
For Zeta potential measurements the Isoelectric point is also indicated at the top
of the graph. This is the pH point at which the Zeta potential is zero.
Please see the Size description in the Zetasizer Nano manual for details on altering
the graph.
Manually controlling the Titrator
A manual measurement is where all the measurement parameters are set immedi-
ately before the measurement is performed. This is ideal if measuring many differ-
ent types of sample, or experimenting with the measurement parameters and
different levels of titrant addition.
To perform a manual measurement, select Measure-Manual from the menu bar.
A manual measurement dialogue will appear where the measurement settings can
be chosen and, if required, saved as an SOP. Once chosen, the measurement can
begin by simply pressing the
Start button on the Measurement display .
