Identification of plastic types for separation is key to effective recycling, and Raman spectroscopy offers the speed and specificity to help. In this application note, the WP 785 ER extended range Raman spectrometer is introduced as a tool to discriminate between plastic types, due to its spectral range well beyond the fingerprint region, its high sensitivity and signal-to-noise ratio (SNR), and excellent reproducibility. It shows the ability of this extended range Raman spectrometer to identify the chemical nature of plastic items down to the exact variety within some of the more diverse polymer families, and the presence of additives.
