Particle SizeAnalyzer
PSA Series

Particle Size Analysis
by Laser Diffraction
Our PSA series has more than 50 years of experience to lean on. In 1967, theworld’s first laser diffraction particle size analyzer, the PSA, was invented. Today,
our three models – PSA 990, PSA 1090, and PSA 1190 – are designed tomeasure a wide range of particle sizes in liquid dispersions or dry powders.

The PSA instruments stand out for their broad particle size measuring range and theirrobustness due to:Multiple-laser technology

Flexibility to measure in dry and liquid mode with one setupPermanently aligned optics

Accessibility and easy maintenance

PSA PRODUCT FAMILYThe laser diffraction technique is an established method to measure particle sizes from theupper nanometer to the millimeter range. A laser beam is first directed onto dispersed particles.
Then, the laser light is diffracted by the particles, and the corresponding diffraction pattern isdetected and evaluated. Our PSA instruments work with high-resolution detectors to provide
accurate and re­pro­ducible measuring signals that are used to calculate particle size distributions
based on the Fraunhofer and Mie theories. This guarantees full compliance with the ISO 13320
and USP <429> standards.

The PSA series covers a broad field of applications in practically any industry.
Whenever quality control of powder materials or emulsions is needed, PSA offersa quick and reliable solution to monitor the particle size distribution. Additionally,
the PSA series serves as an indispensable method in R&D to optimize the final
product properties related to particle size distribution.

Cement and building
materials
A request from the cement
industry to develop a newtechnique for particle size
measurement led to thedevelopment of the first PSAinstrument. To date, therequirements haven’t changed,
and the instruments are stillwidely used in the cement andbuilding industry. The cast-ironbase plate makes the systemrugged enough for use in
the harshest environments.
Additionally, the dry sample
path doesn’t have a sample
cell, meaning there are noglass surfaces that could get
scratched by abrasive samples.

Mining and minerals
In the mining and minerals
industry, the robust design of
the PSA instruments comes intoplay. All optical components
are mounted on a cast-ironbase plate to ensure thesystem remains in alignment
even under the harshest
conditions. PSA 990’s standard
measurement range of 0.2 μm
to 500 μm is ideally suited forthe needs of this industry. The
integrated ultrasonic transducer
is an effective tool to deagglomerate samples.

Pharmaceuticals andcosmetics
Accurate, repeatable, andtraceable measurements arecrucial for pharmaceuticalapplications. To ensure
the highest accuracy andrepeatability, all PSA particle
size analyzers are calibrated
according to the ISO 13320
and USP <429> standards.
The software complies
with 21 CFR Part 11 forcomplete traceability ofresults. PSA 1190’s extended
measurement range of 0.04 μm
to 2,500 μm lets you analyze
the widest range of particles,from raw materials to final
formulations.

Food and beverage
Particle size is an importantparameter that affects thecharacteristics of food products.
Our PSA instruments provide
important information for
production, inspection of raw
materials, product development,and quality control. ThePSA 1190 particle size analyzer
covers a measuring range from0.04 μm to 2,500 μm, letting
you characterize both small andlarge particles. The “free fall”
module, specifically designed
for fragile food samples,
ensures the non-destructive
transport of the sample to themeasuring patch. This means
even large and fragile particles
stay intact during sample
dispersion.

Chemical and petrochemical
Companies in the chemicaland petrochemical industries
are challenged with analyzing
a wide range of materials. Only
our laser particle size analyzers
fully integrate liquid and dry
dispersion modes, meaning you
don’t need to manually switch,
adjust, or align any hardware,
which saves you valuable time.
Solutions are available for all
types of samples, including
aggressive or expensive
products and reagents. What’smore, the liquid sample pathcontains a robust quartz glass
measurement cell without an
inner coating. This reduces
the risk of physical abrasionof the glass to a minimum andeliminates the risk of chemicalabrasion.

Technical Highlights

Need to measure in both liquid and dry mode?
Both are integrated into one instrument
PSA instruments are the only particle size analyzers that canbe configured with fully integrated liquid and dry dispersion
modes in one instrument. This unique design eliminates theneed for the operator to handle several accessories or makemanual adjustments. The software lets you switch between
liquid and dry dispersion modes with a single click, saving
you time and preventing operator errors. You don’t need to
exchange the hardware, revalidate, or realign sensitive optics
when switching between dispersion modes.
Need fully reliable results?
You can rely on the PSA series
Fully compliant with ISO 13320, our particle size analyzers
give you traceable, accurate, and repeatable results.
Whether running samples in dry or liquid dispersion
modes, the complete analyzer is qualified using certified
reference materials. The unique design of the lasers and theoptical bench set the market standard for a measurement
reproducibility that is better than 1 % variation. Accuracy andreproducibility are guaranteed for its entire lifetime.
Need stability for a lifetime?
Don’t think twice about it
The unique optical bench design has all optical components
permanently mounted on a cast-iron base plate. This ensuresalignment-free operation, even in the harshest environments.
The rugged design ensures that the system remains aligned,
which reduces maintenance requirements to a minimum forthe entire life of the instrument. Beyond this, the glass-free
path of the dry mode, along with the robust measurement cellof the liquid mode, mean you have to rarely – if ever – replace
the measurement cell.

Need to measure difficult samples in dry mode?
The Dry Jet Dispersion technology is your answer
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 air flow in accordance with the sample properties. The
shear forces created by the air flow separate agglomeratedparticles. This way, the size of each single particle can bedetected.
Need a wide particle size range?
PSA has you covered from nanometers to millimeters
The single-laser PSA 990 covers a wide measuring rangeof 0.2 µm to 500 µm. For an even wider 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 has an additional third laser tocover the full measurement range of up to 2.5 millimeters.
Need maintenance in your own hands?
It’s easier than everSince they’re easy to open, cleaning and maintaining PSA
instruments is simple and fast. For dusty environments –where regular cleaning is required – this is critical. Besides
this, the liquid cycle has a peristaltic pump that isn’t at riskof cross-contamination because sample can’t accumulate init. You can also replace all of the liquid cycle’s hoses on yourown, giving you a perfectly clean start, whenever you need it.
