Moisture and organic solvent sorption has a large impact on the mechanical, physical, and chemical properties of many materials.

This workshop will highlight a series of water and organic solvent sorption characterization methods for determining the hydrate and solvate formation of different materials. During this presentation, we are going to highlight a series of examples of hydrates and solvation formation and stability. Moreover, we are going to present a case study of solvate formation performed with DVS and in situ Raman spectroscopy.

Using a novel dynamic flow configuration, this gravimetric experimental system can measure both competitive multicomponent adsorption as well as water sorption and glass transition processes. This characterization technique can not only be used across a wide range of materials at different temperatures but is well suited for adsorption studies using organic vapors at high partial pressures.

Agenda:

  • Basic description of the DVS and the standard method of data collection
  • Focused analysis on the theoretical and practical measurement of isotherms of hydrate and solvate formation
  • Description of the technology that enables the DVS to perform this type of measurement (Speed of Sound sensor)
  • Case study of in situ Raman and DVS sorption measurements on the formation of a hydrate and a solvate
