PSA Series

Full description
Anton Paar’s PSA series incorporates fifty years of experience. The world's first laser diffraction particle size analyzer – the first-ever PSA – was invented in 1967. The three models PSA 990, PSA 1090, and PSA 1190 are designed to measure a wide range of particle sizes in liquid dispersions or dry powders.
Key Features

Multiple-laser technology for a wide range of particle sizes

This multiple-laser technology provides you with an extensive range of measurable particle sizes. 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.

Wet and dry samples with just one setup

PSA instruments are the only particle size analyzers that can be configured with both 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. There is no need to exchange the hardware, re-validate, or re-align sensitive optics when switching between dispersion modes.

Accurate size distribution of powder particles

The size distribution of dry powders is often difficult to measure because the particles tend to agglomerate, which falsifies the results. Dry Jet Dispersion (DJD) technology is Anton Paar’s patented technique (FR2933314) for efficiently dispersing and precisely analyzing powder particles. The innovative design features an air pressure regulator that quickly and easily adjusts the air flow in accordance with the sample properties. The shear forces created by the air flow separate agglomerated particles, and in this way the size of each single particle can be detected.

Accuracy, repeatability, and stability for a lifetime

Anton Paar’s particle size analyzers are fully ISO 13320 compliant to meet your requirements for traceable, accurate, and repeatable results. The unique design of the lasers and the optical bench set the market standard for a measurement reproducibility that is better than 1 % variation. Furthermore, the unique optical bench design has all optical components permanently mounted on a cast-iron base plate. This ensures alignment-free operation, even in the harshest environments. Thus, accuracy, reproducibility, and stability are guaranteed for the entire life of the particle size analyzer.



Optional accessory for PSA


Autosampler





Anton Paar’s autosampler for the PSA series is the only sampler on the market that can be used for both wet and dry dispersions, and is able to automate the sample measurement process. Available for the PSA 990, PSA 1090, and PSA 1190 models, the autosampler picks up and pours samples automatically into the particle size analyzer, enabling you to focus on other tasks. The autosampler is equally suitable for industrial as well as lab applications.

Key Features

Dry powder and liquid dispersions in one run
The autosampler can be filled with both wet and dry samples. The software lets you define whether the sample is to be measured in liquid or dry mode.
Automatic pick-up and pouring of up to 30 samples
Up to 30 samples can be processed in one high-rate measurement cycle. Such a procedure saves time and eliminates the risk of manipulation through the operator and thus avoids errors.
User-friendly operation
The autosampler is operated via the PSA software. Everything is integrated; you don’t need additional software to control and run the autosampler. The operation is very intuitive and user-friendly – a measurement cycle is set up within a few minutes and can be repeated with just one mouse-click.

Small Volume Unit





The Small Volume Unit (SVU) was specially designed for users who need to reduce the measured sample volume, e.g. of costly samples. Only 40 mL of sample is necessary to measure accurate particle size distributions. The SVU is also suitable for aggressive solvents such as acetone or benzene.

Key Features


  • Integrated mechanical stirrer, peristaltic pump, and ultrasonic probe

  • Solvent volume of down to 45 mL (PSA 1190) / 40 mL (PSA 1090, PSA 990)

  • Sample quantities of down to 50 mg
