Abstract
Advice for sorting separating and sizing very small particles is disclosed and claimed. The device comprises a cryogenic chamber within which particle movement, travel and separation can occur; a particle loading chamber for loading particles into the cryogenic chamber; and a particle collector. Also disclosed and claimed is helium, and more specifically helium in its superfluid state, for separating the particles.
Claims42
A device for separating very small particles by size, comprising, in combination,
- a cryogenic chamber within which particle travel and separation can occur,
- a loading chamber connected to the cryogenic chamber for loading particles into the cryogenic chamber, and
- a collector device connected to the cryogenic chamber for collecting at least some of the particles after they have been separated by size.
A method of sorting very small particles by size, comprising the steps of providing a column of very low viscosity high wetting fluid, introducing a plurality of particles of various sizes into the fluid in the column, causing the particles to travel through the fluid so as to separate the particles by size, and harvesting the separated particles of desired size.
A batch of particles wetted by helium.
A superfluid having therein a plurality of very small particles.
The use of a superfluid helium to separate and sort particles.
The use of helium to separate and sort particles.
