A Head-to-Head Comparison – Spectradyne’s nCS1TM vs Optical Tracing and Dynamic Light Scattering
The Spectradyne nCS1 is the only bench top nanoparticle sizing technology that provides high-resolution size distributions and accurate concentration measurements for particles in the 50 – 2000 nm diameter size range. The technology employs a novel implementation of the resistive pulse sensing method to rapidly count and size individual nanoparticles in a sample, with typical […]
Where’s my Peak? – Spectradyne nCS1
Separating truth from fiction in label-free measurements of EV’s Introduction As therapeutic and diagnostic applications of extracellular vesicles (EVs) proliferate, accurate characterization of the size and concentration of EV populations becomes more and more critical. Scanning Electron Microscopy (SEM) techniques are often employed but are expensive and slow. Flow cytometry is accurate but requires labelling. […]
Particle Analysis Instruments for Food QA/QC
Quality assurance and control (QA/QC) of food goods is a tightly-regulated issue worldwide. It must be conducted at every stage of production, from harvest and transportation to processing and packaging. Hazard analysis and critical control points (HACCP), shelf-life determination, research and development (R&D) into new product recipes. Each of these processes benefits from advanced particle […]
Importance of Powder Flow in Cosmetic and Personal Care Products
Cosmetics and personal care manufacturers consume enormous volumes of both synthetic and organic powders every year. These vary from clay minerals and starches to synthetic polyethylene powders, each of which may be used in their raw form, blended with additional powdered materials, or integrated into a continuous- or solid-phase end-product. The variations in cosmetic and […]
Particle Shape Analysis with FlowCam Image Analysers
The various particle shapes within a sample may be indicative of its origin, or its physio- and biochemical characteristics. However, samples are often characterised with respect to particle size rather than morphology. Typical counters use a standard volumetric characterisation technique to measure the concentration of particles in a sample, which requires a singular measurement for […]
Zeta Potential Analysis of Coconut Milk
The most enduring challenge in the food and beverage industry is achieving an objective measure of quality for subjective attributes such as flavour and texture. This is complicated by broad-ranging and enduring societal changes that have forced manufacturers to re-think their product recipes and improve their plant-based offerings. At the outset of 2019, the charity […]
Christmas Material Characterisation: Analysing Chocolate with Meritics
Indulging in chocolate has become a festive staple, from advent calendars and selection boxes to bracing mugs of hot chocolate. There is a measure of subjectivity to our enjoyment of chocolate-based products, but there are numerous neurocognitive benefits of chocolate-consumption that go beyond personal perception. Material characterisation of the chemical relationship between chocolate and neurocognitive […]
3 Applications of Powder Flow Analysis
Understanding powder flowability is complicated by the common misconception that the flow properties of any powder product exist somewhere on a linear spectrum, i.e. between nonflowing and free-flowing. In fact, powder flow is a dynamic and multivariable characteristic. It is dependent upon myriad factors including particle size and size distribution, particle morphology, and powder composition. […]
RM200 Rheometers for Food Industry Applications
The rheological properties of food products are key for determining instability mechanisms that may impact their texture or flavour, texture, and shelf life. Often these characteristics are assessed using viscometers, which determine the viscosity of products with fluidic properties under pre-defined experiment conditions. This is a limited method when it comes to testing products of […]
