Polymer Characterization

The use of polymers is so pervasive that nearly all industries have a need for Polymer Analysis either regularly or on an as-needed basis.

What are Polymers?

Polymers are large molecules comprised of many repeating units.  These units are  joined together to form really long chains.  Polymers can be natural, for example cellulose,  starch, and nucleic acids.  Polymers can also be synthetic, such as Nylon, Polystyrene, and Polyethylene.  At SGS Polymer Solutions we have decades of experience in the field of polymer analysis coupled with strong educational backgrounds.


Chromatography:  Chromatography analysis separates mixtures into individual components, for example, polymer and additives.

Spectroscopic: methods answer the question, “what is it?

Microscopy:  Microscopic methods provide information about polymer size, shape, and structure of materials and surface topography information.

Physical Testing:  Physical test methods provide performance information for samples under specified test conditions.  For example, “how strong is it?”

Wet Chemistry: Wet chemistry covers a large variety of testing techniques.  Wet chemistry methods are often a necessary part of a more complex testing plan.

Thermal Analysis:  Thermal analysis methods determine physical properties as a function of time, or frequency, and temperature in a controlled atmosphere. For example, “what is the melting point?”

Titrations:  Quantitative chemical analysis for a particular analyte. For example, “how many acid groups are present?”  We can perform Potentiometric Titrations, Halide Testing, and Karl Fischer Titrations.
