In order to be able to perform practical analyses and comparisons, droplet aerosols must be generated from liquids that are also used in the real world. Fluids, such as water, DEHS, motor oils, white oil, etc., differ significantly in viscosity, surface tension, and density.
The PLG system uses a a nozzle system specially developed by Palas® based on the Laskin principle, which guarantees highly constant particle size distributions and particle concentrations over long periods.
Various model versions have been developed for different applications. Depending on the model, the liquid can be heated to temperatures of up to 120°C and atomized with various nozzles to different maximum mass flows of up to approx. 3 mg/h – 300 g/h. The nozzle can also be used at positive pressure values of up to 10 bar.
In addition, the aerosol generators are able to be equipped with an automatic refill unit to enable the aerosol material to be dispersed over several days.
