IGA-003-MC Binary Gas Sorption Analyzer

GRAVIMETRIC SORPTION ANALYZER FOR BINARY GAS SORPTION ANALYSIS USING THE IMB METHOD

• Unique IMB method used to measure binary gas adsorption isotherms
• Single component and binary equilibria measured in one experiment
• Only a few grams of sample required
• Precise control of pressure, composition and temperature conditions
• Fully automated operation, including integrated mass flow and MS calibration routines

INTRODUCING IGA-003-MC

The IGA-003-MC is a turnkey system for binary sorption analysis using Hiden Isochema’s IMB (Integral Mass Balance) analysis technique. Featuring a gravimetric analyzer, coupled mass spectrometer, and an optimized gas delivery and sampling system.

KEY FEATURES

• Dynamic mode gas delivery with gas flow calibration
• Dedicated sample reactor with combi bath / heater for sample thermostatting
• Optimized sampling interface with a close-coupled Hiden mass spectrometer
• Recommended sample size is 2-3 grams for operation in the pressure range 0.5 bar to 10 bar
• Unique IMB method for partial uptake determination

THE IMB METHOD

In the IMB method, a controlled gas mixture flows over a sample suspended from the IGA microbalance and the gas composition at the outlet is determined using a mass spectrometer (MS). Inlet flow rates and outlet gas composition are then combined with in-situ gravimetric data to calculate the partial uptake of each gas – as well as total uptake – as a function of molar fraction. Full time-dependent data is recorded and analyzed to ensure steady state conditions are achieved at each step of the measurement. The IMB method is unique to Hiden Isochema’s IGA-003-MC binary gas sorption analyzer.
