Particle Concentration Analysis of Microplastics

16/05/2018

The concentration of non-degradable plastic products in the world’s oceans is impossible to accurately quantify, but localized research indicates that plastic pollution levels are currently vastly underestimated. These approximations account for polymer-based products from macro- to micro-scales, with emerging research focusing increasingly on the dangers presented by microplastics. Microplastics are tiny polymer particles that have […]

Outlining Laser Diffraction Particle Size Analysis

10/05/2018

Multiple technologies and methods exist for performing particle size analysis with the intention of testing the mechanical, chemical, or biophysical properties of a sample. These methodologies include dynamic light scattering (DLS), permeability measurements, and laser diffraction particle size analysis. Laser diffraction particle size analysis is a common technique applied to measure particles ranging from nanometer […]

Using Permeameters for Environmental Applications

02/05/2018

Modern environmental studies face a multiplicity of problems including the breadth of the sector itself, which encapsulates numerous disciplines and methodologies from across the world. Disparities between national or cultural priorities makes it difficult to draw accurate conclusions about the state of human interaction with global ecological systems – which is why it is important […]

Applications of Permeability Measurements

27/04/2018

Permeability refers to the porous characteristics of an organic or inorganic material, incorporating a sample’s susceptibility to both liquid and vapor. Various measurement methodologies exist for the determination of a sample’s permeability via a permeameter, which uses both liquid and gas flow systems. In a typical permeameter, a sample will be loaded into a chamber […]

Outlining Dynamic Light Scattering

18/04/2018

Particle analysers rely on a range of analytical techniques to determine the dimensions and the mechanical or biochemical characteristics of various samples. Emulsions and particles in suspension are commonly measured using dynamic light scattering (DLS), a method capable of defining the size and shape of particles, as well as their concentration and/or vector when dispersed […]

How Do Particle Size Analysers Determine Material Characterisation?

11/04/2018

There are copious methods of particle assessment for material characterisation, with different samples requiring varying techniques and methodologies to ascertain its viability for use in a consumer or industrial product, or for research purposes. Particle size analysers are subsequently varied, relying on different instrumentation to perform accurate analyses of particle morphology to further determine the […]

Performing Zeta Potential Measurement

04/04/2018

The electro-kinetic potential of colloids is known as its zeta potential. This is the difference in charge repulsion/attraction between mobile particles in a dispersion fluid, and the stationary layers of ions which have attached to the surfaces of insoluble nanoparticles dispersed throughout the medium. Zeta potential measurement is performed by dispersing nanoparticles in a liquid […]
