Introduction
This specification covers the Mastersizer in its most basic form i.e. without any
details of the sampling accessories. Details on the specification of the accessories
can be found in their individual accessory manuals. This specification covers both
the Mastersizer X and Mastersizer S - any information that is specific to a
particular model is given separately.
Particle sizing specification
The Mastersizer X has an overall size range of 0.1 - 2000 micron covered in four
ranges. The Mastersizer S has an overall size range of 0.05 - 3500 microns covered
in three ranges.
The table below gives these ranges.
Mastersizer X Mastersizer S
Lens Size range Lens Size range
45mm 0.1 - 80 µm 300RF 0.05 - 900µm
100mm 0.5 - 180 µm 300mm 0.5 - 900µm
300mm 1.2 - 600 µm 1000mm* 4.2 - 3500µm
1000mm* 4.0 - 2000 µm
* The 1000mm lens is only available on the long bench Mastersizers only.
It should be noted that accessories may have individual size range limits that are
more restrictive.
Dynamic range. 17600:1 maximum for the Mastersizer S, and 800:1 for the Mastersizer X
on a single measurement.
Accuracy. ±2% on Volume Median Diameter (measured by an approved technique
using a diffraction reference reticle).
Measurement
data.
Up to 45 light energy measurements for the Mastersizer S and 31 for the
Mastersizer X from a custom design semiconductor detector optimised for
light scattering measurement. In addition a centre ring reading measures
the unscattered light energy for determination of the obscuration.
