Aerosol and Spray sizing

The Malvern Spraytec provides real-time particle size distribution of sprays and aerosols. This laser diffraction system is specifically designed for spray characterisation providing;

Accurate Particle Sizing: over a dynamic range of 0.1 - 2000 microns using just two lens systems.
Rapid Measurements: one measurement every 100 microseconds (10kHz) fully captures transient changes in both pulsed and continuous sprays.
High Concentration: patented multiple scattering correction ensures spray measurements can be made even at high concentrations.

Spraytech with nasal spray actuator

The long optical path can be customised for different spray geometries, such as wide plumes. A range of triggering options means that measurements can be synchronised with delivery devices and spray actuators. The IP rated housing protects against dust and water and a compressed air purge prevents contamination of the optics.

Spraytech software fully controls the process from automatic alignment, background subtraction, triggering, measurement, to the final data analysis. The Size History function enables particle size trends to be easily compared and quantified. Measuring parameters can be incorporated into Standard Operating Procedures (SOPs) to ensure all users follow exactly the same methods. Full validation is provided including compliance with 21 CFR Part 11
