Note
This is the instrument confirming which type it is. In brief, if the instru-
ment name contains an
S
it tests
size
and if it contains a
Z
it tests
zeta
potential
. A Zetasizer Nano
ZS
or
ZS
90 tests both.
Fill the cuvette and/or cell
Prepare the appropriate cuvette/cell for size and/or zeta potential measurement as
described here. For example, if the instrument reported just now that it will test
only zeta potential measurement, skip the
Size test
procedure below.
Important
Always hold the cuvette or cell near its top, not the optical area
near its base. Fingerprints, grease or dust on the lower area will
cause the test to fail.
