CPS Spectrometer

The CPS DC24000UHR high resolution disk centrifuge with automatic sample injection system is used to measure particles in a liquid medium. This centrifuge separates particles by size using centrifugal sedimentation within an optically clear spinning disc in sucrose gradient.  Particles sediment within the optically clear, rotating disc; when they approach the edge of the rotating disc, the particles block/scatter a portion of a light beam that passes through the disc. The change in light intensity is continuously recorded and is converted by the operating software into a particle size distribution. This instrument is suitable for analyzing the size of a wide range of particle types, such as metal, polymer, protein, lipid, virus, as well as cells and cellular fragments.


Projects are initiated by a meeting of the user, principal investigator, Core Director and Core Manager.  Contact Mr. Tej Shrestha.  
The Core provides individual training.  
Trained users coordinate instrument use via the Scheduler.



Nanotechnology core facility equipment use is currently free for properly trained persons, with approval of the lab manager.  However, a fee structure will be implemented long-term.  This fee structure is expected to be similar to that of the other core labs on campus.
