Particle Characterization

Particle analysis at the touch of a button

Particle systems can be complex, but measuring them doesn’t have to be! Anton Paar offers two different technologies to characterize particles from the nanometer to the millimeter range. The Litesizer series employs light-scattering technology to determine particle size, zeta potential, transmittance, molecular mass, and the refractive index of nano- and microparticles in liquid dispersions. The PSA series uses laser diffraction technology to measure the size of particles in both liquid dispersions and dry powders in the micro and millimeter range. Side by side they open up a wide range of possibilities for comprehensive particle characterization.

5 Reasons

The Litesizer series: Two instruments, up to five modes

The Litesizer™ particle analyzers open up many particle analysis options: You can use the instruments in up to five different modes to measure particle size, zeta potential, molecular mass, transmittance, and refractive index.

The PSA series: Measurement of liquid and dry samples with just one instrument

PSA instruments are the only particle size analyzers that can be configured with fully integrated liquid and dry dispersion modes in one instrument. You can switch between the two modes with just one mouse click – no need to exchange the hardware, re-validate or re-align sensitive optics. This saves time and prevents operation errors.

Sensitive optics protected by the robust design

The highly sensitive measurement optics of both instruments are mounted in a tightly encased optical bench or on a cast-iron plate. This ensures alignment-free operation and accurate detection of even low-intensity signals, also in the harshest environments. Furthermore, the measurements remain unaffected by dust or temperature fluctuations, and maintenance efforts are reduced to a minimum throughout the entire life of the instrument.

The intuitive software reduces the operator involvement to a minimum

The Kalliope™ software displays all input parameters and gives you measurements and analyses on a single page. In this way all important information is at hand. With this intuitive software you are free to concentrate on what your particles are doing instead of trying to figure out how to use the instrument. With the PSA instruments you are able to switch between liquid and dry modes with just one click and, in combination with the sample changer, you can even automatically operate a serial measurement. Kalliope™ is 21 CFR Part 11 compliant for complete traceability of results.

Dedicated accessories allows for measuring small sample volumes, organic solutions, batches, etc.

There are a number of different cuvettes available for the Litesizer™ to measure e.g. zeta potential and particle size of particles in organic as well as in aqueous solvents and also very low volumes of down to 12 µL. The unique design of the Ω-shaped capillary in the Omega cuvette enables more stable and reproducible results. For the PSA series, there is an automatic sample changer available that is capable of measuring up to 30 wet and dry samples in one run.
