Some industries require strict control of particle size and
particle shape in order to manufacture high quality products. These
industries can benefit from the use of a particle size analyzer
that can also perform shape analysis
This document describes measurement made on plate particles used
in paint industry. The shape of the particles is of first
importance for the paint industries in order to have good shades.
Two samples having the same thickness with two different surface
must be controlled after production.
Size and Shape Characterisation of Plates Particles for Paint
Industries
The CILAS 1180 Particle Size Analyser is ideal for repetitive,
high quality measurements of particle size and shape. Its
integrated wet and dry dispersion modes, built in video camera and
short optical path make it the most versatile instrument available
anywhere. The unique design of the 1180 provides a measurement
range of 0.04 to 2,500 m while maintaining an extremely small
footprint.
Expert Shape software allows the users to calculate many
different parameters from a sample, and to view qualitative
results. Expert Shape for thresholding, contour identification and
binary noise removal. Images of your particles can be stored along
with the particle size distribution data for later retrieval.

The aim of the measurement was to determine the mean diameter of
the particles. The table shows the perfect correlation between the
laser diffraction technology and the CCD values.
The benefits of the CILAS 1180 and the EXPERT SHAPE software
- Shape analysis combined with the Laser particle size analyzer-
Direct comparison of results with the same software - Advanced
tools for data management, statistical analysis and report
generation- Methods and results applicable on other CILAS Particle
Size Analyzer- Implementation of a Standard Operation Procedure-
Permanently aligned optical system- Short bench concept- Full
automated routine analysis- Interactive, user friendly software
The both technologies are complementary. The shape analysis
helps to characterise the process and the laser diffraction allows
to do routine analysis when the process is defined.
