DVS in Combination with In-Line Raman Measurements

ProUmid White Paper

The sorption behavior and the interaction of a substance with water vapor is of great importance for the shelf life, physical and (bio)chemical stability of the product. In addition, product properties such as flow behavior, compatibility, solubility and bioavailability can be significantly influenced by the interaction with water vapor.

Water vapor sorption measurements therefore offer a well-suited method for estimating product properties and changes during the manufacturing and distribution process of a product and controlling them with the help of suitable measures.

White Paper

This application note shows water vapor sorption measurements in combination with inline Raman measurements as a powerful tool for investigating product changes triggered by the interaction with moisture.

The combination of the proUmid’s SPS devices with Raman spectroscopy is an excellent way not only to precisely analyze the moisture sorption behavior of materials, but also to understand moisture-related changes of a product in detail and to monitor them directly with the help of Raman spectra.
