IMI-HTPHigh Accuracy Hydrogen Storage Material AnalyzerThe IMI-HTP is designed primarily for the investigation ofnovel hydrogen storage materials using Sieverts’ Method upto pressures of 200 bar. It offers highly automated sorptionmeasurement procedures, as well as full control over allexperimental parameters. This flexibility enables fullyprogrammable operation throughout the entire measurementpressure range, with the sample temperature controllablefrom ambient up to 773 K. Optional cryocooling can extendthis range down to cryogenic temperatures.The system hardware, including the stainless steelconstruction, all-metal seals, and oil-free vacuum degassingcapability, is specified to meet the challenging demands ofhigh pressure hydrogen operation, while the reactor featurespermanent overpressure protection to satisfy the mostrigorous safety requirements.The instrument’s inherent flexibility allows users tocharacterize the fundamental properties of hydrogen storagematerials by determining PCT (Pressure-Composition-Temperature) relations, kinetic rates of absorption anddesorption, and van ’t Hoff plots for the calculation of sorptionenthalpies. Applied experiments, such as cyclic thermal andpressure stability testing, can then be used to assess thepotential of a material to suit real-world applications.H2 pressure / mbar600005000040000300002000010000333 K343 K353 K363 K373 K383 K00 0.2 0.4 0.6 0.8 1 1.2 1.4Hydrogen content / Weight %ModelKey FeatureMax.
