Polymer, plastics and fibers

Polymers have been utilized as essential components of commodities for a very long time. From naturally occurring products like rubber, cotton and linen, to various synthetic compounds, polymers have been used broadly in the modern world. They include stationery, textile, packaging, toys, automotive, aircraft and construction sectors.

Polymers are engineered to achieve certain characteristics including high strength, toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing and low cost. Depending on the application, material characterizations and control may require the measurement of molecular weight and branching of polymers, the measurement of particle size and morphology of raw materials, both the primary and residual concentration of monomers in an end-product.

The significance of polymer analysis cannot be understated. It is important for quality control, research and development and failure analysis in a vast range of industrial and commercial applications.

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.

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.

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.
