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.
Morphology
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 Homogenizing
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.
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.
