TSI 3482 Electrospray Aerosol Generator

TSI 3482 Electrospray Aerosol Generator

The TSI 3482 Electrospray Aerosol Generator produces high concentrations of monodisperse, submicrometer particles from 2 to 150+ nm (initial droplet diameter of 150 nm, nominal). The electrospray pushes a grounded liquid solution or suspension through a capillary tube into an electrical field. The electric field pulls the liquid from the capillary, creating a Taylor cone and forming individual droplets. Air and CO2 mix with the droplets to evaporate the liquid content. During the drying process, the particles are neutralized using a soft X-Ray neutralizer.
