The Bettersizer 2600 is a compact and highly integrated analyzer of the
latest generation for the analysis of particle size distributions
according to the principle of static light scattering (laser
diffraction). The modular design of the Bettersizer 2600 combines two
widely used sample preparation and supply mechanisms in one instrument.
Depending on the application, the operator can choose between two
detached, fully automatic dispersion modules, being integrated into the
measuring software: BT-802 for wet dispersion in liquid media or BT-902
for dry dispersion by means of compressed air.
Short-wave laser light (635 nm) hits the particles during size
measurement and is scattered elastically dependent on the particle size.
The permanently installed detectors determine the angle dependency of
the scattering intensity in forward, sideways, and backwards direction –
this is enabled by the unique design of the optical bench, based on the
combination of Fourier setup and Inverse Fourier setup. Data editing by
either Fraunhofer or Mie theory delivers the volume-based particle size
distribution of the sample.
