Some tracer particles are already set-up in the Sample-Tracer window under
Tracer Details. These include tracer particles supplied by Malvern and can be
'edited' or 'added to' by the user as required. For Malvern supplied particles the
Nominal Tracer Size is usually the size on the bottle which may differ from the
hydrodynamic size in the sample solvent. This value can be modified by ticking the
Edit box. It is this value which is used in the microrheology calculation.
An optional smoothing window can be applied to the Mean Square Displacement
prior to conversion in to rheological parameters in order to improve the quality of
the final data. This can be found in the
Measurement-Advanced
window and is
set-up to use a 5 point smoothing window as default.
Note:
Both the
Nominal Tracer Size
and
Smoothing Window
can be edited
after the test if required with a new result entry created with the modified
values.
