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.

Access:

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.

 

Fees:

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.
