HTP1-V Volumetric Analyser

Product Overview

The HTP1-V volumetric analyser is specifically designed for high accuracy hydrogen sorption measurements on a range of potential hydrogen storage materials. The instrument offers fully automated operation for the measurement of metal hydride pressure-composition isotherms (PCI) and excess adsorption isotherms for microporous adsorbents.

The system can operate in the temperature range from 103K to 773K, including stable isothermal control at intermediate temperatures, and a pressure range of up to 200 bar. The incorporation of auxiliary gas inputs allowing the use of other sorbates, in addition to the helium used for dead space volume calibration, makes the HTP1-V a versatile high pressure volumetric sorption analysis system.
