Product Overview

The IGA-001 is the core of our range of gravimetric analysers, designed to study single component gas-solid and gas-liquid interactions. The IGA design integrates precise computer-control and measurement of mass change, pressure and temperature to enable fully automatic and reproducible determination of gas sorption-desorption isotherms and isobars in diverse operating conditions.

A range of sample environment options are available to allow operation at temperatures from -196 to 1000 °C  and at pressures ranging from ultra-high vacuum (UHV) to 20 bar. The IGA-001 has been used in a diverse range of applications areas, including gas sorption on carbons and zeolites, gas interaction with ionic liquids and for the characterisation of hydrogen storage materials.

Product Features

• Versatile gravimetric gas sorption analyser, with ultra-sensitive microbalance
• Precise ramp-set-point PID pressure control from one or more high resolution sensors, up to 20 bar
• Stable set point furnace for accurate isothermal operation and low thermal mass furnace for rapid response ramping
• Cryo-cooling option for controlled low temperature operation down to -196°C
• Inert gas loading option for moisture and air sensitive samples
• Readily upgradable to other IGA series models
• Unique IGA method for sorption kinetics and equilibrium isotherm determination

The IGA Method

The IGA method involves continuously monitoring and analysing the weight data following a controlled change in gas pressure. This real time analysis both determines the kinetic parameters and predicts the exact point of equilibrium uptake. The equilibrium points are collected and plotted as an isotherm, giving a consistent reproducible analysis method whilst making optimal use of instrument time.
