Chemical Identification of Resin with Raman Spectroscopy

Posted on: February 27th, 2024

Summary

Raman spectroscopy is a highly valuable and widely utilized technique for real time chemical identification measurement in various molecules and materials. Its non-destructive, rapid, and precise results have made it indispensable across diverse industries such as Pharmaceutics, Forensics, Food, Chemistry and Materials science, Gemstone identification, and Petrochemical identification.

It is important to emphasize that proper calibration methods are being applied for chemical identification measurements to ensure accurate and reliable identification and data interpretation. Therefore, distinct calibration models are required to ensure accurate wavelength, Raman shift and intensity. Once a reliable calibration is performed, it becomes feasible to obtain chemical information based on the peak position, intensity, shift, and width. By leveraging the Avantes Raman spectrometer, an efficient, non-destructive, and accurate chemical detection system can be achieved.

As an example, it is shown here that Raman spectroscopy can be used to identify the chemical structure of specific resins used in the industry. Specifically, the detection of aromatic bonds within the structure are highlighted. Depending on the case, the recommended setup includes the Avaspec-HSC1024x58TEC-EVO, either having a larger wavelength range, or having a better resolution but with a reduced wavelength range.
