Identifying the features Chapter 3
Mastersizer 2000 Page 3-3
The features shown are:
Optical bench
The optical bench is used to collect the raw data used to calculate the size of parti-
cles in a sample.
One or more sample dispersion units
The sole purpose of a sample dispersion unit is to prepare the sample then deliver it
to the optical bench so that it can be measured. Malvern makes many sample dis-
persion units to handle many forms of sample, including dry powders and samples
dispersed in a liquid. A user may have one or more sample dispersion units,
depending on their particular requirements.
In the diagrams above:
The Mastersizer 2000 is shown with two dispersion units, a Hydro 2000G on
the left and a Hydro 2000 S on the right.
The Mastersizer 2000E is shown with a Hydro 2000MU.
The individual dispersion unit manuals identify the dispersion units’ features.
Computer system
The computer system is a stand-alone computer that runs the Malvern software.
The Malvern software controls the optical bench and dispersion units (apart from
the Hydro 2000MU and Scirocco 2000M which are manually controlled). It also
analyses the raw data from the optical bench to determine the size of the particles.
