Chemical compatibility
Components of the Zetasizer Nano that may come into contact with the sample are
manufactured from materials that are considered to give the widest protection from
chemical attack. However, it is important to check that any sample or titrant used is
chemically compatible with the materials mentioned.
Warning!
It is advisable that the chemical compatibility is checked against the materi-
als identified below before inserting a sample. It is also recommended that
a test is performed on the material with the sample before more permanent
usage is undertaken.
Any cleaning and maintenance procedures necessary are described in the
Mainte-
nance
section of the
Health and safety
chapter.
Cell area
As the sample measured is held within the cuvette or cell used, all components
within the cell area will only come into contact with the sample if spillage occurs.
The materials list below details all components that may comes into contact if this
occurs.
Cells and Cuvettes
Refer to the descriptions in the
Zetasizer Nano Accessories guide
for the mate-
rials used for each of the available cells.
