Laser diffraction testing of aerosol
Laser diffraction
The instrument is equipped with an inhalation cell which enables withdrawal of aerosol particles/droplets into the measurement zone using a standard flow control unit or by using a lung.
All types of devices can be assessed with this technique. In addition to the standard output parameters, Dv10, Dv50, and Dv90, it is possible to evaluate the aerosol emptying time and volume from the device. Anatomical throat models can also be used in the set up so that the measurement is performed on the “lung dose”.
