Measurement Types

Particle size distribution

Particle size analysis in the range 0.01-3500 microns. For nanoparticle analysis see dedicated section.


Morphological analysis of particles in the range 0.5-10000 microns (size, shape and transparency of particles). Integrated Raman chemical analysis with MDRS (Morphologically Directed Raman Spectroscopy).

Nanoparticle characterization

Size, concentration and zeta potential anlysis of nano-systems using light scattering techniques such as DLS, ELS and NTA techniques.

Rheology, Viscosity and Powder Flowability

Viscosity measurement and visco-elastic properties characterization of liquid dispersions, complex fluids and semi-solid materials.

Stability analysis

Rapid and objective quantification of concentrated dispersion real stability using Multiple Light Scattering.

High pressure homogenizer

High pressure homogenizing technique to produce stable nanoemulsions, reduce particle size or molecular weight of polysaccharides, nanoencapsulation, de-agglomeration, etc.

Exosomes and EVs characterization

Multiparametric characterization of exosomes and EVs including Sizing, Concentration per size range, Count, Phenotyping, Cargo, Integrity, Purity, etc.

Biomolecular interactions

Biomolecular interactions of proteins, antibodies, nucleic acids, lipids and other biomolecules using ITC Microcalorimetry or BioLayer Interferometry BLI techniques.

Protein aggregate analysis

SEC is the standard method for protein aggregate analysis. The choice of pore size is related to the size of the molecule to be separated.

Polymer characterization

Gel permeation chromatography (GPC) that separates analytes on the basis of size, typically in organic solvents. The technique is often used for the analysis of polymers.

Elemental analysis

XRF provides both qualitative and quantitative information on a wide variety of sample types. It can quantify elements from beryllium (Be) up to americium (Am) in concentrations from 100% down to sub-ppm level.

Phase identification

Phase identification is the most important application of X-ray diffraction (XRD). It is not only applied on powder samples but also on polycrystalline solids, suspensions and thin films.
