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'
