1. Fourier and Reverse Fourier optical system
Bettersizer 2600 particle size tester is characterized in particular by its unique and innovative optical bench design: the light focused on the detectors through the lens is scattered by particles and detected in both forward and lateral directions (Inverse Fourier structure). In contrast to conventional laser diffraction devices, the backscattered light passes through the lens a second time. In addition, the cuvette is positioned at an angle of 35° to the incoming laser light.
This smart setup allows, on the one hand, the detection of scattered light in a very wide angular range from 0.016° to 165°. On the other hand, in contrast to a pure Inverse Fourier structure, the particles do not have to lie in one plane – the simultaneous exact measurement of small and large particles is therefore achieved.
2. Intuitive and powerful software
3. Wet Dispersion
Laser diffraction method conforming to ISO 13320
In a wet measurement, the particles are dispersed in a liquid medium in the dispersing module, additional dispersion may be performed by an ultrasonic disperser.
Various external modules are also available to achieve this purpose:
4. Dry Dispersion
Dry dispersion is used when dry powders or granules are to be measured without the use of solvent. During sample preparation, the sample is pre-dispersed by a vibrating transmission channel, it falls into a channel and is transported by compressed air (venturi nozzle) through to the horizontal measuring cell. Dispersion is carried out by particle collisions with the wall of the container and particleparticle shear. Switching dispersion modules is easy. Simply remove one module and replace it using its handle. Dry dispersion is also possible with a variety of external modules:
