Particle characterization solutions by Anton Paar

Particle size analyzers
Particles can be complex, but measuring them doesn’t have to be. The Litesizer and PSA series enable particle size measurements at just the touch of a button, and much more:
- Litesizer series: Dynamic light scattering for particle size analysis from the lower nanometer up to the micrometer range including zeta potential, molecular mass, transmittance and refractive index measurements
- PSA series: Laser diffraction for size analysis of liquid and dry dispersions up to the millimeter range
- Dedicated accessories allow measurements with small sample volume, in organic solutions, using automatic sample transfer, etc.
- Focus on your particles: Kalliope software serves both instruments and reduces operator involvement to a minimum

True powder rheology
The two cells for true powder rheology, the powder flow cell and the powder shear cell, in combination with MCR Evolution rheometers help you to really characterize and understand your powders:
- Amazing precision of the renowned MCRe rheometers for powder analysis
- High reproducibility due to sample preparation modes and fully automated measurements
- Multiple measurement modes for both quality control and scientific purposes
- The only shear cell which can be equipped with temperature and humidity options

Adsorption analyzers

Experts from the start
As broad as the particle characterization portfolio of Anton Paar is, many instruments have one thing in common: They have been the first of their kind and are still the flagship instruments in their field. For example, PSA, invented back in 1967, was the first particle size analyzer using laser diffraction technology. The first commercial small-angle X-ray scattering (SAXS) camera, developed by Otto Kratky in 1957, was manufactured by Anton Paar. Today, Anton Paar SAXS systems are still the benchmark when it comes to this technology. Quantachrome Instruments, a brand of Anton Paar, started to make its way to the top in 1968. Ever since then, dedicated teams of scientists have developed innovations in close contact with users, resulting in the best possible solutions for measuring porous materials and powders.
