WHITEPAPERM alvern Instruments WorldwideSales and service centres in over 65 2015 Malvern Instruments LimitedA basic guide to particle characterizationPARTICLE SIZEPARTICLE SHAPEI ntroductionThe aim of this guide is to provide you with a basic grounding in the mainparticle characterization techniques currently in use within industry andacademia. It assumes no prior knowledge of particle characterization theory orinstrumentation and should be ideal for those new to particle characterization ,or those wishing to reinforce their knowledge in the area. The guide coversintroductory basics, particle characterization theory and particle characterizationinstrumentation, as well as a quick reference guide to help you decide whichtechniques might be most appropriate for your particle characterization is a particle ?At the most basic level, we can define a particle as being a discrete sub-portionof a substance. For the purposes of this guide , we shall narrow the definition toinclude solid particles , liquid droplets or gas bubbles with physical dimensionsranging from sub-nanometer to several millimeters in most common types of materials consisting of particles are: powders and granules pigments, cement, pharmaceutical ingredients suspensions, emulsions and slurries vaccines, milk, mining muds aerosols and sprays asthma inhalers, crop protection measure particle properties?
Particle size measurement is routinely carried out across a wide range of industries and is often a critical parameter in the manufacture of many products. Particle size has a direct influence on material properties such as: • reactivity or dissolution rate e.g. catalysts, tablets
