The standard aerosol
generation is important for the PM2.5 monitors calibration. Various techniques
are known for aerosol generation such as Atomization method, Fluidized Bed methodand Agglutination method.

However, the limitations
of these traditional methods must be focused that Atomization method could only
be applied to powder materials dissolved easily in liquid, the Fluidized Bed
method is well known for the unevenly distributed aerosol particles, and the
Agglutination method is only applicable to the particular materials with
reaction characteristic. A new approach is therefore needed in the generation
of PM2.5 standard aerosol. The generation of nano-micron particles based on
supercritical fluids, especially the PGSS approach, has made a great progress
in recent years. Read more>>>>>>>
