y, Quevedo and Pfeffer [114] introduced
a new method through which in situ agglomerate size
measurements and the imaging of fluidized
nanoagglomerates were achieved by reducing the electric
charge in the bed and using Focused Beam Reflectance
Measurement (FBRM) and Particle Vision Measurement
(PVM) probes. The probes successfully characterized the
number weighted and volume weighted agglomerate size
distributions for both APF and ABP type nanoparticles.
The FBRM data and PVM images showed that the
probes were capable of differentiating between different
types of nanoparticles (APF and ABF) and could also
evaluate the effects of the microjet assisting method on
the agglomerate concentration and size.
