DVS Adventure Water Vapour Sorption Analyser - Good Condition

DVS Adventure: the water vapour sorption analyser for scientific research

The DVS Adventure from Surface Measurement Systems is a laboratory instrument designed to analyse the dynamic sorption of water vapour on solid samples. This technology is based on a gravimetric method that measures changes in the mass of a sample as a function of the ambient water vapour concentration. By precisely adjusting the relative humidity around the sample, the system allows real-time monitoring of absorption and desorption processes. This approach is particularly useful for studying the stability of hydrated forms, humidity-induced phase transitions, and the amorphous content in solids. The DVS Adventure offers exceptional mass resolution, down to 0.01 µg, and remarkable thermal stability, ensuring reproducible and reliable results.

A complete solution for complex materials

The DVS Adventure is suitable for a wide variety of materials, ranging from pharmaceutical solids to polymers, composites, cellulosic materials, flavourings, woods and sorbents. It can be used to study permeability, diffusion, sorption kinetics and complex isotherms. Thanks to its thermal chamber, which can be controlled between 5°C and 85°C, it avoids condensation problems and ensures perfect temperature homogeneity. The instrument is also equipped with an integrated preheater that can reach 200°C for drying or activating samples in situ. This device is essential for dehydration and rehydration studies at very low relative humidity, particularly below 1% RH.

Modularity and precision for in-depth analysis

The DVS Adventure stands out for its modular design, which allows the integration of accessories such as Raman spectroscopy, IR spectroscopy and video microscopy. These modules enable images and spectra to be captured during sorption experiments, providing a multidimensional understanding of the phenomena under study. The control software allows complex experimental sequences to be programmed, with temperature and humidity cycles, ramps or plateaus, and customised mass variation criteria. Data analysis is facilitated by integrated tools for studying isotherms, diffusion, permeability, specific surface area, and sorption heat. The DVS Adventure is therefore an indispensable tool for researchers wishing to finely characterise the physicochemical properties of their materials.
