The BI-DCP Particle Size Analyzer from Brookhaven Instruments

Brookhaven Instruments has introduced a high-resolution, digitally controlled particle size distribution analyzer called BI-DCP. The advanced analyzer provides high-resolution results in the size range between 0.01 and 30 µm, with standard analysis times spanning from 5 to 30 minutes.

The DCP (Disc Centrifuge Photosedimentometer) software enables easy instrument control, database management and data analysis. The menu-driven software allows a wide range of report formats. Brookhaven Instruments is known for providing light scattering instruments that are specifically designed for the characterization of sub-micron particle sizing and polymers.

The company has identified the need to create high resolution in the size range of 1 µm and keeping this aspect in mind, it has designed an instrument, the resolution of which exceeds any other method in this range.

Sedimentation is essentially a fractionation method and the BI-DCP analyzer offers a method to isolate the components of mixtures and also define an array of distributions.

Features at a Glance

  • Stable, easy and fast operation
  • Overcomes particle sizes in complex mixtures
  • Well-suited for a variety of densities and sizes
  • Calibration is not needed and precise derivations are obtained
  • Internal and external gradient
  • A wide range of operating modes
  • Enables successive injections of samples
  • HOST or LINE start methods
  • Variable rotation speed
  • Scanning or stationary detector
  • Experimental conditions can be improved in advance
  • Weight distributions are quantitatively determined
  • Constant monitoring of temperature
  • Modifiable reports and analysis

No other technique has the ability to resolve this many closely spaced-peaks.

The BI-DCP analyzer integrates a customized electronic drive system with excellent efficiency and, at the same time, operates quietly on the benchtop.

A built-in strobe light is synchronized to the drive circuit to assess the hydrodynamic stability of the sample. Furthermore, a sensor is used to track the disk temperature. The BI-DCP system provides the largest range of speeds, from 500 to 15,000 rpm, allowing an even higher range of particle size measurements. Measurement time is reduced by a scanning detector head.

Benefits of Use

An instrument is considered an investment in both the present and future. The BI-DCP analyzer is indeed affordable because it allows users to:

  • Track incoming raw materials to minimize rework
  • Overcome complex particle size distributions to improve structural and rheological characteristics
  • Boost cost-effectiveness by decreasing the scale-up and process time
  • Fingerprint the end products to reduce lot-to-lot variations
  • Analyze the fundamentals of particle size to design innovative processes and products
  • Improve material properties to further improve the performance of products
