AMSORB® Plus is the world’s first CO₂ absorbent to be free of strong alkali.
It offers significant clinical, cost and environmental advantage.
AMSORB® PLUS is NOT a soda lime
The primary reaction is between CO2 and calcium hydroxide (Ca(OH)2) and water. These form calcium carbonate (CaCO3) and water. Exothermic heat is a by-product of absorption. During absorption, Ca(OH)2 is continually re-moistened until converted to CaCO3. Lesser chemicals, calcium chloride (CaCl2) and calcium sulphate (CaSO4) prolong the life of Ca(OH)₂ and increase the speed of absorption reaction by maintaining granule strength and optimising hydration.
Slightly soluble >>>>> Insoluble
The ions are Ca++ and OH-OH-
CaCO3 is an insoluble ionic compound Ca++ and CO3- –
Reactions take place in solution when particles are mobile and react on collision.
A colour indicator is present, changing from WHITE (fresh) to VIOLET upon exhaustion or desiccation.
The indicator reacts to changes in granule hydration as absorption progresses; eventually remaining violet-coloured, once absorption is complete. Colouration also results from contact with ambient air or oxygen, if exposed to these.
