Optical particle size analyzer Vasco™

dynamic light scattering

The VASCOTM nanoparticle size analyzer is a unique instrument for nanoparticle suspension and colloidal characterization, based on the Dynamic Light Scattering (DLS) . Key benefits High detection efficiency in opaque/dark media, as well as in diluted solution thanks to a DTC patented system Extended sample concentration range (up to 40%*) Reduce sample preparation (no filtration or dilution) Polymodal and complex sample analysis No consumable Solvent-proof sample cell Technologies & innovations VASCO combines : Unique embedded sample cell made of a silica prism and backscattered light detection Dual Thickness Controller (DTC) : patented system allowing measurement of diluted sample as well as dark / concentrated ones, without dilution Flusher to remove dust and bubbles Advanced Padé Laplace algorithm Main characteristics Based on Dynamic Light Scattering (DLS) Particle size (diameter) : 0,5 nm – 10 μm Sample concentration : 0.1ppm – 40%w/v * Optical filter option to improve measurements on fluorescent samples On-line sample cell option → size kinetics study NanoQ proprietary software Compliant with ISO 13 321 – Particle size analysis – Photon correlation Spectroscopy & ISO 22 412 – Particle size analysis – Dynamic Light Scattering
