New IGA ECOsorp Brochure Now Available!

We’re pleased to introduce the new IGA ECOsorp brochure, now available to download. The IGA ECOsorp is a compact, high-performance sorption analyzer designed specifically for carbon capture research — combining precision CO₂ and H₂O sorption measurements with exceptional stability and ease of use.

Key Features

1. Independent control of CO_₂ and humidity across Direct Air Capture (DAC) and Post-Combustion Capture (PCC) conditions, allows assessment of sorbent materials under relevant environments.
2. Barometric compensation technology ensures true CO_₂ partial pressure measurement and control, compensating automatically for ambient pressure fluctuations.
3. Widest CO_₂ control range of any benchtop sorption analyzer, the ECOsorp offers unmatched flexibility with programmable CO₂ conditions from 100 ppm to 100%, without the need for expensive pre-mixed gas cylinders.
4. Unrivalled sensitivity and stability using Hiden Isochema’s renowned high precision microbalance, offering sub-microgram resolution and exceptional long-term stability.

Performance Data in Action

The brochure includes a range of example datasets that highlight the system’s accuracy and versatility for key carbon capture experiments.

Pure CO₂ adsorption isotherms measured at 25 °C for an ion exchange resin (Lewatit® VP OC 1065), a zeolite (13X powder) and an activated carbon (NORIT ROW 0.8mm pellets). Samples were dried in situ under dry gas flow at appropriate temperatures prior to the isotherm measurements. Isotherm points were recorded at CO₂ partial pressure points from 0.1 mbar (100 ppm) calculated from the measured fractional CO₂ flow rates and the IGA ECOsorp’s Barometric Compensation Technology.

Co-adsorption H₂O/CO₂ isotherms for the ion exchange resin together with the corresponding pure CO₂ isotherm. For each measurement the sample was dried in situ and pre-equilibrated with water at the defined relative humidity, prior to introduction of CO₂ at partial pressures shown, with the relative humidity maintained for the remainder of the isotherm. Total amounts adsorbed were calculated from the combined number of moles of CO₂ and H₂O, assuming the H₂O adsorbed in the pre-loading step remained in place.

Time dependent kinetic data from a simple gravimetric sorption-desorption isothermal response test for an ion exchange resin at 25 °C. Water was introduced at 2.5 and 5.0 %RH (blue trace), followed by the addition of CO2 at 100 and 400 ppm (green trace). The process was then reversed, and the sample mass can be seen to return to the initial dry state.

This dataset highlights how the ECOsorp’s independent control of humidity and CO₂ concentration enables precise evaluation of competitive adsorption processes — an essential factor in developing efficient carbon-capture materials.
