T1 - Development of a device for staged determination of water activity and moisture content N2 - Moisture content and water activity are important parameters of product characterization; thus, an exact determination is necessarily required in a wide range of industrial applications. Moisture content of materials is the content of non-chemically bound water in a solid or liquid. Water activity (aW) is a characteristic/parameter of the non-chemically bound ("free") water in materials and is measured as humidity over a solid/liquid surface at constant temperature (equilibrium moisture content). It is an important parameter to characterize the quality of pharmaceutical and food products. In our contribution, we present a developed device for staged determination of water activity and moisture content of liquid and solid materials.
