It is possible to discriminate particles on the basis of their effective refractive index. Thus, a precise and quantitative analysis of numerical particle size distributions of single populations is possible, moreover avoiding artefacts due to invention algorithms, as required in traditional particle sizing methods, such as Dynamic Light Scattering (DLS), Static Light Scattering (SLS) and MultiAngle Light Scattering (MALS). High accuracy and resolution on the numerical particle size distribution are possible also for heterogeneous samples in biological fluids, where the presence of solid content complicates, if not prevents, any characterization measurement with traditional approaches.[/vc_column_text][vc_column_text css_animation=”fadeInLeft”]

SPES/SPES² measurements of analytical replicates of standard particles are useful for the quantification and the validation of the reproducibility within the sample preparation error.[/vc_column_text][vc_column_text css_animation=”fadeInLeft”]
