One of the principal analytical techniques for identifying polymers is infrared (IR) spectroscopy. We deliver a family of advanced instruments, from the Spotlight™ 200i and Spotlight 400 IR imaging systems to the portable, fast, and easy-to-use Spectrum Two™ IR system, all outfitted with ready-made protocols, a materials library, and unique Spectrum Touch™ software. These are the instruments of choice for researchers involved in the identification and quantification of synthetic polymer microbeads, as well as for analyzing other compounds in water – everything from visible plastic to below-100 µm microplastics.
An important factor in identifying the source of a microplastic particle is the additives used to enhance polymer performance. A common technique is thermal analysis or pyrolysis, combined with GC/MS for high-sensitivity analysis of polymers and their organic additives (as well as characterization of particles below 100 µm). ICP-MS analysis is also used for identification and analysis of inorganic additives in the plastic.
Typical applications in microplastic particle characterization include:
For research use only. Not for use in diagnostic procedure.
