BI-DCP – Disc Centrifuge Photosedimentometer

The Brookhaven BI-DCP Disc Centrifuge Photosedimentometer (DCP) is a digitally controlled, high-resolution, particle size distribution analyzer. It yields high-resolution results in the size range from 0.01 to 30 microns with typical analysis times ranging from 5 to 30 minutes. The BI-DCP software provides easy instrument control, data analysis, and database management. The software is menu-driven and permits a variety of report formats.

Brookhaven Instruments is renowned for light scattering instruments dedicated to sub-micron particle sizing and polymer characterization. Having identified the need to produce high resolution in the 1-micron size range, Brookhaven has produced an instrument with a resolution unmatched by any other technique in this range. Sedimentation is intrinsically a fractionation technique and the BI-DCP Particle Size Analyzer provides a means to separate the components of mixtures and also characterize a wide variety of distributions.

No other type of instrument can resolve several peaks in the difficult range of around 1 micron.

The DCP incorporates a custom electronic drive system with high efficiency while operating quietly on your benchtop. An integral strobe light is synchronized to the drive circuit to check the hydrodynamic stability of the sample. A sensor is used to monitor the temperature in the disk. The BI-DCP offers the largest range of speeds, 500 to 15,000 rpm, which allows an even greater range of particle size measurements. A scanning detector head reduces measurement time.
