The measurement of water activity (Aw) is a very important metric in the food industry. It is used by food manufacturers and government agencies to evaluate the quality of food ingredients and to predict a product’s potential shelf life. The most widely used method to determine Aw is the measurement of water vapour pressure emanating from a food material enclosed in a sealed chamber. This application note demonstrates a possible alternative to the traditional method employed by industry and describes advantages that may be gained by this new procedure.

The surface properties of powders and fibres are important parameters in the handling and performance of a wide range of solid materials. iGC SEA has been specifically designed to address many of the issues faced by physical properties researchers, including fully automated operation and the ability to measure samples in a controlled humidity environment. This Application note gives a brief description of the technique, the instrument and some examples of its application to a range of polymeric materials analysis problems.

In the present paper dispersive surface energies and specific free energies have been calculated for different modified E-glass fibre surfaces. Both different sizing and different polymer coatings have been investigated to consider changes in the surface chemistry and surface energy during different fibre treatments.
Finite concentration IGC SEA is a useful tool for the investigation of surface and pore properties. A novel combination of finite concentration IGC SEA and thermal desorption provides the possibility to separate micropore adsorption from surface and mesopore adsorption. This allows the calculation of BET values with physical relevance for highly microporous materials and the consideration of molecular sieve effects.
The glass transition temperature Tg is an important property for the characterisation of polymeric, food, pharmaceutical and many natural products. iGC SEA can provide a fast and accurate determination of this property as well as its dependence on relative humidity. This paper describes the characterisation of maltose with decane at infinite dilution.
The surface energy is a useful parameter describing the energetic properties of the surface of a solid sample. It can be determined in a fast and accurate way by IGC SEA. This paper describes the measurement of the dispersive component of the surface energy of Paracetamol.

Biomass, such as wheat straw is an abundant and inexpensive natural biopolymer rich in cellulose and hemicellulose  which can be converted into bio-fuel. The bio-fuel has been attracting attention due to the future potential shortages of fossil fuel [2,3]. One of the crucial steps of producing bio-ethanol from wheat straw is its pre-treatment which should facilitate the economic feasibility and yield efficient conversion into biofuel. This pre-treatment is expected to increase the accessible chemical sites of the straw to increase convertibility in subsequent hydrolysis and fermentation steps. Dynamic Vapour Sorption (DVS)  and UV were used to assess the wheat straw pre-treatment and sugar yield, respectively.
Raman spectroscopy is a widely used physical characterization technique used in the pharmaceutical industry. The combination of Raman spectroscopy and Dynamic Vapour Sorption (DVS) allows for a more complete understanding of vapour-solid interactions for pharmaceutical materials as it relates to structural properties. This paper overviews the DVS-Raman capabilities and gives several examples.
DVS is now established as a useful analytical tool in many R&D laboratories throughout the world. This application note describes the integration of DVS with a colour video microscope for the in-situ visualisation of moisture induced morphological transformations, which may be correlated with the gravimetric data.
The Dynamic Vapour Sorption(DVS) provides potential benefit over the COST 90 procedure. This application note compares DVS Results to COST 90 procedure.
Validation of humidity generation and measurement in gravimetric vapour sorption instrumentation is an important issue for the pharmaceutical and related industries. This application note sets out a standard DVS method for validation of relative humidity data using saturated salt solutions.
