Brookhaven Instruments BI-DCP



The Brookhaven BI-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 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 resolution unmatched by any other technique in this range. Sedimention is intrinsically a fractionation technique and the BI-DCP 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 around 1 micron.

The DCP incorporates a custom electronic drive system with high efficiency while operating quietly on your bench top. An integral strobe light is synchronized to the drive circuit for checking hydrodynamic stability of the sample. A sensor is used to monitor 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.

Benefits of Use
An instrument is an investment in the present as well as in the future. The BI-DCP is truly cost-effective because it enables users to:
  • Resolve complex particle size distributions to improve rheological and structural properties.
  • Monitor incoming raw materials to reduce rework.
  • Fingerprint finished products to minimize lot-to-lot variations.
  • Increase cost effectiveness by reducing process and scale-up time.
  • Optimize material properties to enhance product performance.
  • Study particle size fundamentals to develop new products and processes.
