Quality comparison of different CO2 absorbents

A comparative investigation into the quality and properties of six brands of CO2 absorbent was performed. The six investigated brands were: Aldalime, Baralyme, Drägersorb, Durasorb, Medisorb and Sodasorb. The following quality factors were investigated: the CO2 absorption capacity, dust content, the flow resistance and the colourshift. The circumstances under which the absorbent is used in the clinic were simulated as much as possible.
