Spray droplet size measurement

Malvern’s Spraytec system measures across a wide range of particle sizes (0.1–2000 microns) during real-time spray actuation

The Aerosol Dispensers Directive 75/324/EEC and Cosmetic Products Regulation (EC) 1223/2009 require manufacturers to assess the potential risk to humans of product use for ‘normal and reasonably foreseeable exposure routes’.

For aerosols this includes the risk of inhalation, a factor that is overridingly influenced by particle and droplet size.

Malvern’s Spraytec system measures across a wide range of particle sizes (0.1–2000 microns) during real-time spray actuation.

Capable of resolving rapid changes in droplet size over time by taking up to 10,000 measurements per second, the technique is eminently suited to testing spray and atomization processes for aerosol devices.
