IGA-003-MC

Description

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.

BENEFITS OF IGA-003-MC

- 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

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.

KEY FEATURES

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
