WebAug 17, 2024 · FTIR (Fourier-transform infrared spectroscopy) is commonly used to analyse thin films and multilayer materials. However, as layers become increasingly thinner (for example in packaging materials, especially in the food industry), the spatial resolution of FTIR is often insufficient. WebFTIR spectroscopy is a flexible, useful tool in the manufacturing and processing of polymer pellets and films. This webinar will focus on uses of FTIR in support of QA of polymer production, whether by drawing discrete samples or via continuous monitoring. Topics include: Overview of polymer analysis by FTIR.
