Pore Size Measurements for Powder Metallurgy Raw Materials


Pore size measurements must be conducted on the raw materials for powder metallurgy processes, to ensure that end-products yield desirable mechanical properties. The strength, weight, hardness, and permeability of metal alloys produced from powder minerals depends upon the porosity of the raw constituents. Powder Metallurgy and the Importance of Pore Size Measurements Powder metallurgy refers […]

Laboratory Services: Surface Area Analysis with Meritics


Surface area analysis is one of the leading particle measurement techniques for characterising the behaviour of solid samples. The surface area of a solid particle represents its primary interface with other media, including gaseous and liquid molecules. It is, therefore, a crucial parameter in the determination of a particle’s adsorption and dissolution characteristics. Typically, surface […]

BET Surface Area Analysis for Catalyst Analysis


Catalysis refers to the acceleration of a distinct chemical reaction using a catalytic agent. It has been an integral process in a range of industrial sectors for decades and is attracting interest from fields looking to reduce emissions and tackle issues pertaining to sustainability. The primary consumers of catalytic materials worldwide are chemical manufacturers, petrochemical […]

Sample Analysis: Particle Size Measurements with Meritics


Sample analysis can be a complex process that typically requires significant up-front investment and ongoing maintenance or calibration. It is an essential process for laboratories and commercial facilities that need products to be evaluated and characterised with regards to their particle characteristics, their fluidic properties, or their long-term stability in response to thermodynamic influences. This […]

Modular Laser Diffraction Analysis with the LS 13 320 XR


The LS 13 320 XR is the most advanced laser diffraction particle analyser on the market, operating with full implementation of the Fraunhofer and Mie theories of light scattering. This provides reliable quantification and characterisation of particles on the sub-micron scale, with a potential dynamic sizing range of 0.01 – 2,000 micrometres (µm). Alternative technologies […]

The effect of bean origin and temperature on grinding roasted coffee


Abstract Coffee is prepared by the extraction of a complex array of organic molecules from the roasted bean, which has been ground into fine particulates. The extraction depends on temperature, water chemistry and also the accessible surface area of the coffee. Here we investigate whether variations in the production processes of single origin coffee beans […]

Particle Analysis Instruments in Water Treatment


The purification of drinking water is a multi-step process that typically requires cleaning with a biochemical or catalytic agent and filtration through a solid phase media. This process is doubly complicated by the varying requirements of different water sources. Groundwater may contain significant volumes of suspended particulates such as salt or geological sediment, while water […]

Dynamic Light Scattering for Exosome Characterisation


Extracellular vesicles are an overarching species of biological structures that are associated with intercellular communication. These organisms exist on the micron (μm) and submicron (nm) scale and are released by healthy cells into the extracellular environment to facilitate one of many microbiological processes, including coagulation, phagocytosis, and apoptosis. Scientists have been aware of extracellular vesicles […]

Particle Analysers for Pigment Sizing


An industrial pigment is an organic or synthetic mineral used to tint a material and alter its spectral absorption characteristics. Essentially, they change the colour of a product via selective wavelength absorption or transmittance. These desirable chromatic properties are ideal for use in manufacturing, visual arts, and engineering commercial products such as inks, paints, cosmetics, […]
