Tracer measurement
The
Tracer measurement
SOP window is similar to the standard zeta potential
Measurement window. Where appropriate please refer to the
Measurement
description in the
zeta potential SOPs
section of the main user manual for more
details on each of the measurement options.

Description
Tracer
measurement
duration
The
Tracer measurement duration
options are the same as
standard measurement duration options available during
normal zeta potential measurements.
Tracer
measurements
The
tracer measurements
options define the number of
repeat measurements that can be made at each
measurement distance from the sample surface, and the
length of any delay between these repeat measurements.

displacement
The final stage in a surface zeta potential measurement is a
fast field reversal (FFR) only measurement. The purpose of
this is to make a measurement
only
of the tracer mobility,
which will not include any electro-osmotic component, and
this will be used in the surface zeta potential equation.
