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.
