Spectradyne Nanoparticle Analysis Webinar – Where’s my Peak?


Does your current particle analysis technique show you a “peak” in your exosome distribution or protein aggregate data? Have you ever suspected that this “peak” might not be real? Join our 30-minute webinar on 11 July 2018 to learn how microfluidic resistive pulse sensing (MRPS) can give you the most accurate picture. We will demonstrate […]

Particle Size Analysis in the Pharmaceutical Sector


Pharmaceutical products are comprised of tightly-controlled ratios of biologically active ingredients and excipient materials, the latter of which are designed to act as a drug carrying vehicle. The relationship between these compounded chemicals is critical in understanding drug dosage and efficacy, with multiple parameters affecting the ideal composition values of bulk medicinal products. Particle size, […]

Outlining Powder Flow Analysis


Powder flow analysis is a method for determining the material properties and characteristics of powdered solids in bulk. Bulk powders exhibit vastly different mechanical attributes in dynamic or static states, behaving with mutable characteristics under varying conditions. Compressed, static powders often display similar properties to consolidated materials – yet when that same substance is subject […]

The Applications of Dynamic Light Scattering


Light can typically travel uninterrupted through a homogenous liquid sample, even if it is refracted or if the color of the liquid absorbs some of its wavelengths. This is because transparent liquid particles will transmit light rather than reflecting it. If a liquid sample contains nanoparticles or particulates however, these microscopic solids will block and […]

Particle Concentration Analysis of Microplastics


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


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


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


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


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 […]
