particle classification and separation techniques

Particle Classification and Separation using Cryogenics 

The NHMFL cryogenics group has initiated two experimental R&D efforts directed toward using cryogenic fluids as media for the classification and separation of micron and sub-micron size particles.  Particle classification involves determining the size distribution of an ensemble of particles while separation focuses on selection of a particular size range from a broader distribution.  Separation of materials according to material density is also an area of current interest.  However, current conventional technology for particle separation becomes ineffective for particles much below a few microns in diameter.  Cryogenic fluids may assist with these goals.

The current project in this area is:
