Disc Centrifuge Chosen to Enhance Particle Characterisation Capability

Analytik are pleased to announce that ParticlesCIC at the University of Leeds, have expanded their range of particle and

material characterisation instrumentation to include the CPS DC24000 Disc Centrifuge. The ParticlesCIC is an established centre with an enviable track record of providing routine and problem solving services to industry; it is one of 12 accredited ‘Centres of Industrial Collaboration’ in Europe. Escubed Ltd, a spin out company from the ParticlesCIC that specialise in providing research services, will also have access to the instrument as they look to strengthen their analytical capability.

The CPS Disc Centrifuge is able to resolve multi-modal particle distributions with clean separation of narrow peaks that differ in size by as little as 2%. This ultra high-resolution performance is completely unique and offers the possibility to detect and measure extremely small changes and differences in particle size, especially in the sub-micron particle size range. Depending on particle density the CPS Disc Centrifuge can accurately and reproducibly measure particles between 2nm and around 75 micron. The CPS instrument also has high sensitivity, with a minimum detection limit below 10-8 gram active sample for narrow peaks, and analysis of samples of a few micrograms active weight is routine. With this level of high resolution, sensitivity and reproducibility, the range of applications is broad: powdered (water soluble) drugs andmedications; virus particles; protein molecule clusters and virus-like particles (to below 20nm); polymer latexes (aqueous) with any particle density; emulsions of oils and waxes; ground and precipitated calcium carbonate; inorganic pigments and fillers; and ground sucrose, starch and flour.
