IGA-003 MC: Measuring Binary Gas Adsorption Isotherms with the Exclusive IMB Technique

The gravimetric sorption analyzer utilizes the IMB method for binary gas sorption analysis.

Benefits of IGA-003-MC

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

Introducing IGA-003-MC

The IGA-003-MC is a turnkey system that employs the IMB (Integral Mass Balance) analysis method from Hiden Isochema for binary sorption analysis. It comprises an enhanced gas delivery and sampling system, a coupled mass spectrometer, and a gravimetric analyzer.

Key Features

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

The IMB Method

In the IMB method, a mass spectrometer (MS) is used to determine the gas composition at the outlet after a controlled gas mixture passes over a sample suspended from the IGA microbalance.

The partial and total uptake of each gas is then determined as a function of a molar fraction by combining in-situ gravimetric data with outlet gas composition and inlet flow rates. Full time-dependent data is recorded and analyzed to ensure that steady-state conditions are achieved at every step of the measurement.

The IMB technique is a distinctive feature of the IGA-003-MC binary gas sorption analyzer by Hiden Isochema.
