Re: [PSUBS-MAILIST] ExtendAir scrubber cartridge

[Jon Wallace <jonw@psubs.org>]

Ok.  Let's get past Thanksgiving and then we can start rolling with it.

From memory, Lithium Hydroxide is much better at CO2 absorption but a 
lot nastier substance too and so handling is a concern.  I don't know if 
Micropore's canisters make handling less of an issue or not.  Lithium 
Hydroxide is particularly good at CO2 absorption in low temp situations 
where as soda lime and some others lose efficiency at low temps.  
AND...lithium hydroxide was chemical of choice for the Apollo moon 
program (not an endorsement of the chemical, just a trivia fact).
