Part 2: Running the
Installation T est
Introduction
These instructions show how to make a Size and/or Zeta Potential measurement to test the installation of
the Zetasizer Nano. Work through the steps in the order given here.
1. Power on
If it's not already switched on, turn on the instrument and start the software, as described earlier. Remem-
ber that the instrument must be powered up for 30 minutes before a measurement is made.
2. Unpack the installation sample
Take the Installation Sample syringe labelled "DTS1050" from the pack this document was in.
3. Run the Installation Test macro
When the software has been started, select
a.
Tools-Macros-Installation Test:
Note: the results are saved to a
measurement file named Installation
Test.dts which opens automatically.
4. 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.
The instrument reports what it is going to test:
b.
Size, Zeta Potential or both. Use this informa-
tion to decide which cell(s) to prepare (see step
4).
Note: this is the instrument confirming which type it
is. In brief, if the instrument name contains
an S it tests Size and if it contains a Z it tests
Zeta Potential. A Zetasizer Nano ZS or ZS90
tests both.
Hold it in this area
Do not hold it down here.
