Description
Microtrac’s BLUEWAVE provides accurate, reliable, and repeatable particle size analysis for a diverse range of applications by utilizing the proven theory of Mie compensation for spherical particles and the proprietary principle of Modified Mie calculations for non-spherical particles. The BLUEWAVE is optimized for materials below 1 micron delivering unsurpassed resolution. The BLUEWAVE measures particle size from 0.01 to 2,800 µm. Microtrac has a tradition of delivering innovative solutions in particle size analysis through light scattering technology. The BLUEWAVE Laser Diffraction (LD) analyzer is a continuation of that tradition. Utilizing the patented tri-laser technology, the BLUEWAVE provides accurate, reliable and repeatable particle size information for applications ranging from research and development to production, process, and quality control. The BLUEWAVE complies with or exceeds ISO 13320-1 particle size analysis – light diffraction methods.
FUNCTION PRINCIPLE
The patented tri-laser system allows light scattering measurements to be made from the forward low angle region to almost the entire angular spectrum (0.2 to 165 degrees). It does so by a combination of three lasers and two detector arrays, all in fixed positions. The primary laser (on-axis) produces scatter from nearly on-axis to about 60 degrees, detected by a forward array and a high-angle array, both of which have logarithmic spacing of the detector segments. The second laser (off-axis) is positioned to produce scatter beyond the 60 degree level which is detected using the same detector arrays. The third laser (off-axis) is positioned to produce backscatter, again using the same detector arrays. This technique effectively multiplies the number of sensors that are available for detection of scattered light.
The calculation of the particle size distribution can be done with Fraunhofer or Mie calculation. Microtrac was the first on the market to introduce a special calculation mode to respect irregular shape instead of spherical particles. This algorithm has been further refined for transparent, absorbing and reflecting particles. The BLUEWAVE is fitted with a sample circuit system (Sample dispersion controller) with short paths from dispersion unit to measurement cell to optimize sample flow. The speed of the centrifugal pump can be adjusted according to the viscosity or sedimentation properties of the sample. An ultrasonic tip is integrated and can be regulated by the software. All parameters important to homogenization and dispersion are thus highly controllable. All parts that come into contact with the sample are made from resistant materials like quartz glass, Teflon, stainless steel or Kalrex (chemical compatibility class I). A second integrated pump allows for automatic filling and cleaning.
