Gravimetric Analyzer-Mass Spec (IGA-MS) System

Gravimetric Analyzer-Mass Spec (IGA-MS) System

System Components

  • Feed block: MFC's, HPLC/syringe pumps, heated valves & transfer lines
  • Gravimetric Analyzer Intelligent Gravimetric Analyzer-IGA by HIDEN
  • Analysis block: Mass spectrometer
Analysis mode: in situ / operando

Analysis Examples

  • Determination of adsorption properties and capacities of adsorbents as a function of pressure, temperature and (wet or dry) gas mixture composition (under the flow of gas mixtures having desired composition)
  • Determination of adsorption enthalpy of gases on adsorbents
  • Determination of selective adsorption properties of adsorbents and surface mole fraction of each adsorbate on adsorbent as a fn. of total pressure and temperature for wet or dry gas mixtures of desired composition
  • Adsorption kinetics of gas(es) on adsorbents (for individual gas or wet gas mixture of desired composition)
  • Determination of oxygen storage capacities of catalysts and adsorbents

Parametric Use Cases

  • Optimization of preparation and pre-heat treatment method and parameters
  • Optimization of adsorption properties of adsorbents and solid porous materials
  • Establishing relation between adsorption (especially oxygen storage capacities) properties and performance of the catalysts
