Based on first principle of photo-sedimentation, the Brookhaven Instrument disc centrifuge instruments are the only optical disc centrifuge that measures particle size without calibration. The DCP has a traditional light source and the XDC use X-rays.
These instruments measure the size of particles according to the time the particle takes to sediment in the detector according to Stokes Law. High resolution measurements are typically obtained in 5 to 30 minutes. Modelling software is included to predict optimal experimental conditions like disc speed and run time. The high resolution instrument can resolve peaks as close as a 13% size differential and quantify distribution accurately. No other type of instrument can resolve several peaks in the difficult range around 1 micron. Modelling software is included to predict optimal experimental conditions like disc speed and run time. The instrument can work in line start where the sample is injected on the spinning fluid or the simpler method of homogenous start where all the sample is loaded in the disc and spun.
