82 The ability to use organic vapours opens other applications for the DVS technique with building material. The DVS-Advantage instrument also has the ability to couple in-situ spectroscopy (Raman and/or Near-IR) with the gravimetric sorption measurements. This can elucidate more subtle structural changes in the material (i.e. polymer rearrangement, hydrate formation, polymorph identification or hydrogen bonding). The DVS-Advantage can also couple an in-situ video microscopy. This allows for the investigation of vapour-induced colour change, swelling or phase changes.
83 The DVS Technique is a very fast one compared to older gravimetric methods The DVS obtains very accurate and reliable results It is suitable to study many types of materials, not only building materials Obtains easily sorption and desorption isotherms Can be used to study other phenomena, like permeability, diffusion and phase transitions Can simulate real-world conditions.
