Chemical compatibility
Introduction
The Mastersizer and its dispersion units have been manufactured from materials
that are considered to give the widest protection from chemical attack. However, it
is important to check that any sample or dispersant you may use is chemically com-
patible with the materials that they will come in contact with within the system.
In normal operation the sample and dispersant should not come into contact with
any component of the optical bench (the sample path is contained within the dis-
persion unit and the sample cell). However, if a sample pipe or sealing ring should
fail then sample and dispersant may drip into the cell area of the optical bench. A
drain is fitted in the base of the cell area to limit the spread of any leak.
Should a small leak occur the sample/dispersant may come into contact with the
following materials:
Caution!
The paint finish of the external covers may be permanently damaged if
samples or dispersants are spilt on them. Clean up any spillage immedi-
ately.
