Bettersizer 2600 – Particle Size Analyser

Bettersizer 2600 – Particle size measurement 0.02 – 2,600 µm

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.

Besides the ideal price-performance-ratio, the Bettersizer 2600 offers the following essential advantages:

• Innovative optical system: combined Fourier and Inverse Fourier setup
  Due to the patented setup of the optical system – a combination of Fourier and Inverse Fourier setup – nanoparticles (20 nm upwards) as well as coarse particles (up to 2.6 mm) can be analyzed reliably. The scattered light is detected in forwards, sideways, and backwards direction. The additional skewed measurement cell enables the detection in a continuous angle range, the usage of just one laser delivers a continuous scattering spectrum with consistent wavelength.
• Standard Operation Procedures (SOPs)
  enable an easy and standardized measurement procedure for maximum reproducibility.
• Fast and simple switch from wet to dry measurement
  The change between wet and fully automated dry dispersion of the Bettersizer 2600 with venturi valve and compressor, as well as powder suction, can be executed in less than a minute.
• Automatic laser centering function
  guarantees an ideal adjustment of the optical measurement system for maximum reproducibility.
