The application notes :

001-Measure the Size of Cement Particles Using CILAS 930e PSA

The analysis of particle size distribution is an important economic consideration for the cement industry. About 1% of the worldwide energy production is consumed by the cement industry, more particularly during the grinding step. 

002-Measurement of Certified Cement with the Dry Jet Dispersion Technology

Particle size analysis helps cement manufacturers to optimize the grinding process. In order to verify the accuracy of these devices, the cement industry has established certified cement. 

003-Particle Size Analysis of the Zeolite in Catalysis Industry

Zeolite is one of the most employed elements in the catalysis because of its molecular sieve power and its low cost. The size of the particles is very important for the catalyst. The exchange surface has to be the largest to improve reaction. 

004-Size and Shape Analysis of Metallic Particles in Battery Industries

In the battery industry, the shape and the size of the particles are very important for the electrical properties of the final product. The particle’s morphology can influence their behaviour, their conduction properties 

005-Size and Shape Characterisation of Plates Particles for Paint Industries

This document describes measurement made on plate particles used in paint industry. The aim is to determine the shape factor of two different samples. 

006-Measurement of Pigments with Dry Jet Dispersion Technology

Pigments generally are dry, fine powders that are practically soluble in many usual solvents. Particle size analysis of the pigments can influence some properties such as optical properties, colour and hue. 

007-The Importance of Quality Methods in the Precise Sizing of Microsphere’s Diameter

Different characterization principles are used to measure the size of polymetric microspheres. Taking into account the number of size measurements made daily in the ESTAPOR laboratory, CILAS particle size analyzer is used in regular metrological controls by MERCK. 

008-Particle Size Analysis of Emulsion in the Dairy Industry

The CILAS Particle-size Analyzer is perfectly appropriated to measure fat drops scattered in milk. The particle size analysis is an important factor during process to assure a standardized product at the end.

009-ISO Compliance of the Dry Jet Dispersion Technology

Dry Jet Dispersion Calibration complies with the ISO 13320 standard. Powders traceable to international standard are used: CILAS Secondary Reference and Certified Reference Material from Whitehouse Scientific Ltd.

010-Particle Size Analysis of Cocoa Powders

It is essential to have total control over the particle size of cocoa powders to provide consumers with a product that is pleasing to the eye and to the taste buds.

011-Particle Size Analysis for Drilling in Petroleum Industry

One of the major problems with drilling fluid or mud particularly when reused on different well, is the build-up of very fine micron solids (less than 5 microns). The generation of these particles creates slower penetration rates, high pump pressures, increased solids surface area and the risk is the well becomes stuck and to lose the hole drilled.

012-On-line Measurement of the Size of Silicon Carbide (SiC) Nanoparticles 

The synthesis of Silicon Carbide nanoparticles by laser pyrolysis route creates aggregated nano-objects. The on-line particle size determination permits to limit the nanoparticles exposure and to control the process and avoid a particle size deviation.

013-Choosing the most Suitable Theory in Laser Diffraction - Mie or Fraunhofer

It is possible to use two different theories adapted to the nature of particles. This Application Note is a quick guide to know model limits and consequences of their using on calculated particle size distributions. 

014-Choosing the most Suitable Shape Parameter in Morphological Analysis

In the literature, tens of shape parameters enable the morphology of particles to be characterised. This Application Note is a quick guide to choose the most suitable shape parameter.

015-Combined Analysis of the Size and Shape of Particles in the Pharmaceutical Industry

Many analytical methods exist for the characterization of products manufactured in the pharmaceutical industry. Measuring the size and shape of particles or emulsions is undoubtedly one of the simplest and quickest methods, but provides indispensable qualitative data to assess the feasibility of a manufacturing process or the final effectiveness of a formulation.


Measuring size and shape is part of the precise requirements of the standards taken as the basis for the assessment of the possibilities for particle size analysis techniques and the benefits of morphological analysis for this application.

016-On-line Water in Gasoil Droplet Size Analysis

Water presents in the gasoil can create oxidation phenomenon and modify diesel engine performances. 
The water separation efficiency of filters can be evaluated thanks to the water in gasoil droplet size analysis. CILAS On-Line Particle Size Analyser has been used by IFTS to optimize the new testing method based on laser diffraction that leads to ISO 16332 norm.

017-Particle Size and Shape Analysis of Abrasives in Solar Industry

Abrasives are very useful in many industries. They are for example used to cut wafers to make photovoltaic cells in solar industry. For this application, particle size and shape analysis allows the optimization of wafer slicing which represents an expensive step in solar cells production. 

018-Combining Particle Size and Shape Analysis for a more Precise Particle Characterization

The fast size results provided by laser diffraction and the method's versatility in analyzing a wide range of materials have made it the benchmark particle sizing technology for dry bulk materials. Combining this technique with morphological analysis not only allows to quantify the particle shape but also to control particle agglomeration and dispersion state.

019-Characterization of a Water Oil Emulsion by Laser Diffraction

Emulsions are mixtures of non-miscible liquids that form a dispersion of fine droplets in a continuous phase. Such diphasic systems are very extensively used in a wide range of industrial sectors, such as the pharmaceutical and cosmetics industries, agro-foods or petrochemicals, for example. The particle size analysis of the droplets enables us to fix the conditions for the formation of the emulsion and to assess its stability.
