Gain valuable insight into your product properties with the CPS Disc Centrifuge. Accurately measure particle size distributions in suspensions and emulsions.
From nanometers to microns: accurate particle size distribution analysis
CPS Disc Centrifuge
The CPS Disc Centrifuge uses Differential Centrifugal Sedimentation (DCS) to accurately measure particle size distributions in suspensions and emulsions. Particles are separated based on both size and density, allowing even small differences in particle size to be detected reliably. This provides a detailed view of the complete particle size distribution, including multimodal distributions, agglomerates, and contaminants.
The technique offers significant advantages over laser diffraction and Dynamic Light Scattering (DLS):
High-resolution particle size distribution analysis
Measurement range from nanometers to micrometers
Accurate analysis of multimodal particle size distributions
Reliable detection of agglomerates and contaminants
Typical reproducibility of ±1% or better for reported peak sizes
Excellent reproducibility and long service life
Suitable for both R&D and quality control
Provides insights where laser diffraction and DLS reach their limits
Suitable for liquid dispersions and solid particles after dispersion

Chemical Mechanical Planarization (CMP)
In semiconductor manufacturing, an ultra-smooth surface finish is essential. Chemical Mechanical Planarization (CMP) slurries contain extremely fine abrasive particles, and their particle size distribution has a direct impact on polishing performance. The CPS Disc Centrifuge is routinely used for accurate and reproducible measurement of abrasive particles in CMP slurries by material suppliers, formulators, and semiconductor manufacturers.
