Particle Characterisation


Reproducible Analysis of Particle Shape and Size


Particle measurement is essential in many areas and requires reproducible results. The choice is not always easy and must be specially adapted to the application. For example, Static Light Scattering is ideal for particle sizing from 0.01 to 2100 µm, whereas Dynamic Image Analysis is more suited for analysis of particle shape and size in an extra wide measuring range of 20 µm – 20 mm. Fritsch offers a wide range of particle sizers suitable for all applications.


The ANALYSETTE 22 NanoTec is the ideal Laser Particle Sizer for the determination of the particle size distributions of powdery samples, of solids in suspension and of emulsions.


The ANALYSETTE 22 NanoTec consists of a compact measuring unit that can be quickly and easily combined with different dispersion units for dry or wet measurement. Select the wet dispersion unit for wet measurements of solids and suspensions. For wet dispersion of very small quantities, the automatic small volume wet dispersion unit SVA with illuminated dispersion bath and the compact manual small volume wet dispersion unit SVM are available. The practical, fully automatic AutoSampler makes it easy to perform a series of measurements with the wet dispersion unit. For dry measurements of not too fine, free-flowing materials use the dry dispersion unit with efficient degradation of agglomerates. For dry measurement of agglomerates or free-flowing materials, choose the falling chute


The ANALYSETTE 28 ImageSizer is the ideal Particle Sizer for all applications that require accurate and reproducible measuring results for both particle shape and size of powders and bulk solids as well as of suspensions and emulsions.


The optical process of Dynamic Image Analysis provides results for a wide measuring range, delivers multiple shape parameters and evaluation possibilities for particle size. The measuring time, depending on the sample quantity, is under 5 minutes. And the result is available immediately.


The ANALYSETTE 28 ImageSizer is in combination with the corresponding wet dispersion unit ideal for measurement of particle shape and size of suspensions and emulsions.


The ANALYSETTE 28 ImageSizer is the ideal Particle Sizer for fast analysis of particle size and shape of dry, free-flowing materials. Via the optical analysis of the particle shape and particle size, you can identify damaged particles, contaminates, agglomerates or oversized and undersized particles accurately and fast and view them completely uncomplicated in single images.

Versatile System Provides Fast, Accurate Dynamic Image Analysis


Based on the unique dual camera technology, Retsch Technology’s CAMSIZER P4 measures the size and shape of powders, granules and bulk materials in a range from 20 microns to 30 mm with Dynamic Image Analysis (DIA). Compared to sieve analysis, which only determines the approximate particle size, DIA is superior in its resolution, precision and reproducibility. Moreover, it provides additional detailed information on particle shape.


The DIA technique is much faster than sieve analysis so that production parameters may be monitored and adjusted in real time. A smooth change from sieve analysis to CAMSIZER P4 is easily possible thanks to algorithms for emulating sieve analysis.


The CAMSIZER P4 reliably analyses all size and shape parameters of a great variety


of bulk materials and granulates including spherical and irregularly shaped grains and crystals, spray-dried and fluid bed granular materials, pellets and extrudates.


Thanks to the robust construction and a measuring technique that is not sensitive to disturbances, the particle analyser is also suitable for operation under challenging industrial conditions.


In combination with the optional AutoSampler, efficiency can be increased by high sample throughput due to the automated sample measurement. For dry and wet measurement of particles in a size range from 0.8 microns to 8 mm, Retsch Technology offers the CAMSIZER X2 model which also uses Dynamic Image Analysis.

From less than 1nm to several millimetres, Meritics can provide a comprehensive range of particle measurements for most applications. Small sample volumes and delicate proteins can easily be handled by the Meritics instrumentation range. Particle size, concentration, mobility and molecular weight can be measured in just a few seconds with sample sizes down as small as 3µl. Surface area, porosity, powder flow, and viscosity for paints and powder coatings help to characterise process behaviour and finish.


Meritics can look at biological cells and biopharma materials, dry powders, suspensions, emulsions and colloids from a wide range of industries and research studies providing reliable and reproducible data to help you obtain the information you need for your investigations.


Meritics has a range of laser diffraction particle size analysers for particle size distribution measurement. The new Beckman Coulter LS 13320XR system provides real data down to 0.01µm, while dynamic and static light scattering instruments for sub micron particle size, zeta potential and molecular weight, provide data down to less than 1nm. The company’s dynamic imaging particle analysers provide size distribution and concentration in addition to particle images helping with identification of, for example, protein aggregates in therapeutic solutions.


Particle size and concentration measurements on biological materials from exosomes to lipid emulsions can be measured down to 50nm using the new Spectradyne nCS1 variation on the ‘Coulter Counter’ with just 3µl of sample suspension. For particles from 200nm up to 1600µm the standard Coulter Counter provides unrivalled accuracy and resolution.

Testa Analytical Solutions eK reports that its BI-XDC X-Ray Disc Centrifuge is enabling scientists to make accurate, high resolution particle size distribution measurements, from nanometres to tens of micrometres, without time consuming calibration or absorption correction.


Based on the principle of photosedimentation, the BI-XDC measures the size of particles according to the time the particle takes to sediment in the detector according to Stokes law. Combining centrifugal and gravitational sedimentation in a single instrument the BI-XDC sets a new standard for these well-established methods of particle sizing.


Leveraging a highly reliable orthogonal method, the BI-XDC is proven to give error free quantitative measurements across a broad range of samples including nanoparticles, minerals, clays, ceramics and metal oxides.


Using the Bl-XDC there are no optical corrections and no optical properties to worry about, just a simple mass sensitive response based on x-ray absorption. The BI-XDC features a reproducible digitally controlled disk speed to ensure high performance and accuracy. The proprietary scanning x-ray head enables measurements to be made typically in just 8 minutes.
