How can I calculate the CO2/N2 selectivity of CO2 adsorbents in a fixed-bed rig consisting of a CO2 gas analyser?

How can I calculate the CO2/N2 selectivity of CO2 adsorbents in a fixed-bed rig consist of a CO2 gas analyser (Is it possible to calculate CO2/N2 selectivity from CO2 breakthrough curves while the adsorbent can adsorb N2 as wellAsk)?

Rafael Mattos Dos Santos

If your sorbent is adsorbing both gases, and your outlet analyzer is for CO2 concentration only, then you also need the outlet flow rate to do a component mass balance (you also need the inlet mass flow rates of both gases).
