Anton Paar’s PSA series incorporates more than forty years of experience. The world's first laser diffraction particle size analyzer – the first-ever PSA – was invented in 1969. 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.
Benefit from Anton Paar’s experience in laser diffraction technology for powder analysis! Take advantage of the multiple-laser technology, or the flexibility to measure dry and liquid samples with one setup. The respective PSA product series offers high measuring accuracy and repeatability at an undefeated robust design.
Cement & Building Materials
The PSA instruments, in fact, were designed following a request from the cement industry to develop a new technique for particle size measurement. To date, the requirements have not changed and the instruments are still widely used in the cement and building industry.
The cast-iron base plate makes the system rugged enough to be used in the harshest environments. The patented (FR2933314) Dry Jet Dispersion technology ensures that the particles are homogeneously distributed within the sample. In this way, even cement samples that tend to agglomerate can be measured precisely.
Stability for a lifetime? The unrivaled robust design of the PSA series makes it possible
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. The rugged design ensures that the system remains aligned and this reduces the maintenance efforts to a minimum throughout the entire life of the instrument.
Accurate size distribution of powder particles? The PSA series’ unique Dry Jet Dispersion technology is the solution
The size 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 airflow 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.
Broad particle size range? The PSA series measures particle sizes from sub-microns 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.
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 all PSA 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. The autosampler is fully integrated with the PSA software and guaranties user-friendly operation.
