Performing Zeta Potential Measurement
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 […]
Why Do We Need to Measure Particle Concentration?
Determining the particle characteristics of various products and biological materials is increasingly reliant on the measurement of particle concentration, alongside particle size. It is a crucial metric in a range of industries and academic studies, where products are manufactured to microscopic parameters or where quality assurance – or research – must be maintained and carried […]
Outlining Resistive Pulse Sensing
An important particle characterisation technique, resistive pulse sensing is a high-throughput method used to measure the size and quantity of particles in an electrolyte solution. The Coulter Principle Resistive pulse sensing is based upon the Coulter Principle, which states that the particles pulled through a hole with an electric current produce a change in impedance […]
