Anton Paar offers two instrument series to analyse particle sizes: The Litesizer series and the PSA series. The difference between these series is the measuring principle and therefore the measurable size range of the particles.
The Litesizer series analyses the following parameters via light scattering principle:
- Particle sizes larger than 0,3 nanometers (via dynamic light scattering)
- Zeta potential (via electrophoretic light scattering)
- Molecular mass, refractive index and transmission

The PSA series determines particle sizes in the range from nanometers to 2,5 millimeters in dry or wet dispersion via laser diffraction.
The laser diffraction technique is an established method to measure particle sizes from the upper nanometer to the millimeter range. Anton Paar’s PSA instruments provide accurate and reproducible measuring signals. This guarantees full compliance with the ISO 13320 and USP <429> standards.
Measurement of liquid and dry samples
PSA instruments are the only particle size analyzers that can be configured with fully integrated liquid and dry dispersion modes in one instrument. This unique design eliminates the need for the operator to handle several accessories or make manual adjustments. The software enables the switching between liquid and dry dispersion modes with a single mouse-click, which saves time and prevents operation errors.
The PSA series measures particle sizes from submicrons to a few millimeters
The single-laser PSA 990 covers a wide measuring range of 0.2 μm to 500 μm. For an even broader range, PSA 1090 and PSA 1190 have a unique optical design for diffraction analysis, which includes multiple lasers. While PSA 1090 has been designed with two lasers to resolve particles as small as 40 nanometers, PSA 1190 contains an additional third laser to cover the full measurement range of up to 2.5 millimeters.
