Detecting and Identifying Microplastics in Cosmetics Using IR Microscopy

Microplastic beads are used as abrasive materials in several cosmetic products and are becoming a major water pollutant. The Spectrum Two™ is a type of transportable FT-IR spectrometer so it can be operated from a battery pack and can therefore can be used on boats to instantly identify these polymers.
