Hydrogen Storage Materials - instruments for sorption analysis
The recent explosion of interest in Hydrogen as a clean energy vector has led to an urgent need to develop techniques to handle it. In particular, the safety issues and inefficiency of using Compressed Hydrogen Gas drive a requirement for materials which can hold large quantities of Hydrogen in a trapped state, which can be safely and slowly released as required.
Research into these Hydrogen Storage Materials creates an increasing need for high quality, reliable measurements of hydrogen storage capacity and release kinetics. The Hiden Isochema range of instruments for hydrogen storage materials is at the forefront of this research.
Gravimetric Hydrogen Sorption Analysis
Since its origin, in hydrogen sorption research, the IGA-001 gas sorption analyser has provided the highest quality sorption isotherms and kinetic data, in laboratories around the world. Gravimetry is the method of choice for many of the materials of commercial interest, and the IGA-001 is perfectly adapted to research into materials for hydrogen storage.
Volumetric sorption analysis by Sieverts' method
HTP1-V Volumetric Sieverts' method apparatus extends storage characterisation beyond the effective high pressure limit of gravimetric techniques.
Thermal Desorption analysis
The HTP1-S Thermal Desorption Analyser meets a specific need in Hydrogen Storage material characterisation. The extreme precision available makes possible accurate sorption measurements on tiny samples. Temperature programmed desorption provides valuable information about the energetics of sorption. Additionally, mass spectrometric quantification permits absolute assurance that measured sorption is truly due to hydrogen. Preferential sorption of contaminants or impurities has led to many false trails in sorption science.
