Sorption describes the process by which particles become attached from a fluid phase to a liquid (absorption) or to the surface of a solid adsorbing material (adsorption). The areas of industrial application are very diverse. In pressure swing adsorption plants, for example, adsorption processes are used to generate biogas purification or nitrogen. The food industry applies CO2 adsorption to process foods. Water vapor sorption is of particular interest to the pharmaceutical industry as it is applied to optimize medication storage and production conditions based on the humidity absorption of the material.
In all areas of application, the measurement of the adsorption isotherms plays an important role in course of material characterization.
Isotherm measurement can be performed using gravimetric or volumetric methods. The detection of breakthrough curves also offers a realistic consideration of the technical processes. In this context, RuboLab offers different sorption measurement instruments:
