Laser Diffractometer
- Laser diffraction (low angle light scattering) is a preferred method for
particle size analysis of aqueous aerosols as it is rapid and affords high
resolution.
- The method is well established and relies on the fact that particles
scatter light at angles in inverse proportion to their size (Lorenz-Mie
theory).
- Laser diffraction systems can measure over a wide dynamic range (0.1 to
2000 micrometers).
- The Spraytec (Malvern Instruments) is the latest generation laser
diffractometer which offers the capability of working with optically dense
aerosols that are typically formed by optimized delivery devices, such as
the AeroEclipse* breath-actuated nebulizer (BAN).
