The analyzers are dynamic light scattering (DLS) nanosizing instruments based on a patented innovative technology developed in collaboration with the French Institute of Petroleum (IFP). The VASCO’s original optical configuration design combines back-scattered light detection and the capability to control sample thickness. This design provides higher detection efficiency for opaque sample, decreases the instrument sensitivity to ‘multiple scattering artifact’, and strongly reduces the laser thermal effect allowing very accurate measurements even in concentrated and dark dispersions. In most cases, no sample dilution is necessary which makes measurements almost instantaneous. With its temperature stabilization feature, the VASCO is capable of measuring particle size in a range from 6 micrometers to 1 nanometer.
