Your next packaging analysis tool – Raman microscopy

 

Raman microscopy is a valuable tool for packaging analysis, with special emphasis on food-contact materials. In minutes, you can characterize multilayer material properties such as structure and thickness and can even identify layers with minimal sample handling. In this webinar, we discuss novel promising applications of Raman microscopy, such as:
