BASIC PRINCIPLES OF LASER DIFFRACTION

The light scattering pattern from a group of particles
Laser Diffraction - What do we measure ?

Light Scattering
1. Title 8
A Basic Laser Diffraction System
1. Title 9
Calculating Particle Size
o Laser Diffraction Instrument measures light scattering (not particle size)
o To convert light scattering to Size we need to do some modelling. The two most common models used are: o Fraunhofer Approximation o Mie Theory (Recommended by ISO13320)
1. Title 10
Laser diffraction – getting the result o Light scattering models were developed to calculate
the scattering pattern from a known particle size distribution.
o The Mastersizer measures a scattering distribution and uses Mie theory to calculate Size.
o How do we use scattering theory to arrive at a size distribution from the laser diffraction data?
o We have to back calculate using an iterative inversion process

Dry powder dispersion offers many advantages in terms of simplicity and speed of measurement
o Dispersion mechanism for dry powders depends on: o Disperser geometry o Gas / particle velocity
o Higher impact energies may improve the dispersion effectiveness o Needs to be balanced against the risk of particle break-up
