AMSORB® PLUS CO2 Absorbent How AMSORB® PLUS Works 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. Chemical Reaction of Absorption Ca(OH)2 Slightly soluble Ca(OH)2 is an ionic compound...

Colour Change Colour Change AMSORB® PLUS colour indicator reacts strongly and quickly to the dehydrating effects of CO2 absorption or contact with anhydrous gas, such as oxygen. Whilst the colour change is an indication of the hydrated state and remaining capacity, depletion of the absorbent should be determined by capnometry and the absorbent changed when FiCO2 has exceeded 0.5% volume or 5mmHg. In the case of NaOH-containing (sodium hydroxide) absorbents, colouration reverts to white when contact with CO2 ceases, often after a few hours of non-use. This is due to the strongly alkaline...

Agent Adsorption Agent Adsorption - Patient Awareness Anaesthetic vapour condenses on desiccated soda lime and on new generation absorbents containing molecular sieve zeolites, quartz or silica. This process, called adsorption, temporarily binds anaesthetic vapour within the absorbent. Knolle (2002) reported adsorption using LoFloSorb (Intersurgical, UK) of 89% of the inflow of 0.5% isoflurane for over 60 minutes, in combination with production of CO. Adsorption is characterised by condensing and accumulation of the vapourised agent on the absorbent granules and re-vapourisation of the...

Alkalinity of Soda Lime NaOH Concentration Increases as Soda Lime Desiccates Exponential increases in alkalinity triggers degradation of anaesthetic vapour to toxic inhalants. Safe disposal of soda lime must take account of increases in alkalinity brought about by desiccation. Manufacturers of absorbents cannot declare the pH of their material at any stage, as determination of pH requires the absorbent sample to be converted to a solution. Adding water to a sample of soda lime allows NaOH and NaCO3 to dissolve in water, thus lowering the alkalinity of the material to provide a misleading pH...

Desiccation Retrograde Flow in Absorbents Colouration from Retrograde Flow Colouration from CO2 Absorption AMSORB® PLUS BUBBLE-CAN® UNIVERSAL Gas flow desiccates all absorbents. Retrograde flow occurs when fresh gas flow is left running during nonuse of an anaesthetic machine. Gas may pass over the top of the absorbent canister and desiccate the absorbent. In subsequent use of some absorbents, degradation of the anaesthetic agent may occur in conjunction with agent adsorption. NaOH-containing absorbents will NOT change colour during gas flow desiccation. Instead they remain white but may be...
