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

Powder rheology
Advanced true powder rheology that brings the full array of traditional rheological methods, and decades of experience, into the field of granular media:
- The amazing precision of renowned MCR rheometers, upgraded to a versatile and powerful powder rheometer
- High reproducibility through fully automated measurement modes
- Multiple measurement modes for both quality control and scientific purposes
- Exchangeable measurement systems and flexible software allow characterization from hopper design to segregation testing and state-of-art fluidized bed rheometry

Adsorption analyzers
In adsorption analysis, it is essential to combine both intelligent instrument design and advanced computational data reduction models:

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.
Use the Anton Paar expertise in particle characterization for your particle research and material development.
Along with a wide range of specific instrumentation, Anton Paar offers extensive application consulting as well as application information. Application reports, the Anton Paar Wiki, the Anton Paar Blog, and webinars offer in-depth knowledge on particle characterization topics such as:
- Dynamic light scattering (DLS): The basic concept for measuring the particle size
- Particle size determination
- Particle size distribution
- Basics of laser diffraction (LD)
- Powder rheology
- Nanostructure analysis with small-angle X-ray scattering (SAXS)
- Surface area determination
- Solid density of powders
- How to measure zeta potential with (ELS)
- and many more …
