IGA-100 Integrated Gas & Vapor Sorption Analyzer

This post is also available in: viVietnamese

The IGA-100 is designed for gravimetric mixed gas sorption, as well as single component vapor sorption analysis, and powerfully
combines the features of the IGA-001, IGA-002 and IGA-003. The multiple inlet mass flow controller system allows mixed gas experiments with full pressure and composition control. Anti-condensation protection to 50˚C is also included to allow operation with water and an extensive range of hydrocarbon vapors. As for the IGA-003, an optional vapor generator extends dynamic functionality to include gas and vapor mixtures.

  • Features
  • Applications 
  • Fully programmable with combined control of pressure, flow and gas composition
  • Built-in anti-condensation protection to 50 °C for pure vapor sorption
  • Optional integrated vapor generator module for dynamic vapor sorption (DVS)
  • Sample temperatures from 77 K to 1000 °C
  • Fully integrated quadrupole mass spectrometry option for evolved gas analysis (EGA)
  • Unique combination of vapor sorption options to include DVS measurements with pressure and vacuum control


IGA analyzers are widely regarded as the benchmark for gravimetric sorption analyzers and are used in an extensive range of applications:

  • Gas adsorption capacity determination
  • Moisture and organic vapor sorption
  • Catalyst characterization
  • Moisture and organic vapor sorption with diffusion coefficient determination
  • Thermogravimetric Analysis (TGA) and Evolved Gas Analysis (EGA)
  • Temperature Programmed Desorption/Oxidation/Reduction (TPD, TPO, TPR)

IGA instruments are used in both academic and industrial laboratories globally and are continuously producing high precision reproducible data. The IGA’s reputation is underpinned by publication of data in over 700 peer reviewed papers, including many in high profile journals.
