In this study, macro- and microscopic Raman spectroscopy were used to identify different commercial microplastic fibers using measured spectra with database searches. Raman microscopy is demonstrated as a powerful technique for microplastic fiber characterization, especially for samples that contain mixtures of components, including multiple polymers, or additives.

The motivation for the development of an instrument for transmission Raman measurements is described. The basic instrumentation and the first results from a commercial system are provided. Transmission Raman spectroscopy (TRS) performance is compared to and contrasted with that of a confocal Raman microscope.
