#Malvern zetasizer graphene analyses software

The measurement of the number concentration of colloidal particles is of major commercial interest as it: enables the optimisation of materials specification and design is essential for risk assessment and quality control supports compliance with regulatory requirements and underpins claims to reliability, performance and lifetime in the formulation of products containing particles. Nanoparticles are increasingly used in innovative advanced products and provide enhanced, unique properties of great commercial and societal value. Working with scientists at NPL, Malvern Panalytical could test, validate and benchmark this Particle Concentration analysis feature in the new Zetasizer Ultra and are currently drafting a co-authored journal paper about their findings. We hosted engineers from Malvern Panalytical in the our labs and worked with them using well-characterised nanoparticle materials with known colloidal concentrations already measured by other methods. We were able to provide both the materials and know-how to effect this successful comparison. As one of the industrial collaborators of the NPL-led Innanopart project of the European Metrology Programme for Innovation and Research (EMPIR), Malvern Panalytical was aware of the expertise within NPL and wanted us to help validate this Particle Concentration method and benchmark it against the capabilities of other Malvern Panalytical products. However, the lack of suitable nanoparticle reference materials and traceable methods for measuring colloidal concentrations made the testing and validation of this and similar methods challenging. One of the improved capabilities of this system is the ability to measure nanoparticle concentration, using a combination of multi-angle DLS (MADLS В®) and adaptive correlation.

The flow mode option enables the system to be connected to an SEC or an FFF system to use as a detector for the size of proteins or nanoparticles.ДЄ choice of cuvettes are available, from disposable single-use to specific cells for viscous or high concentration samples or measuring the zeta potential of surfaces. In addition, a microrheology option is available for measuring sample viscosity and viscoelastic properties, as well as a Protein Measurement option for protein mobility measurements. Using Non-Invasive Backscatter optics (NIBS) it has significantly better performance than systems using 90 degree scattering optics. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering. The Georgia Tech Zetasizer Nano ZS, located in the Georgia Tech Biocleanroom, is a high performance two angle particle and molecular size analyzer for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering with вЂNIBSвЂ™ optics.
