Subject: Scrubber preparation for rebreathers

Currently thinking of developing a semiclosed apparatus, I am looking for
some guidelines/recommendations about scrubber materials preparation.

I know that the scrubber material should be compacted at the maximum to
avoid any  "channeling effect" but is there a standard procedure ? Any
other aspect to consider?

Is there a mean to evaluate the scrubber efficiency other than starting a
breathlessness. How to monitor the autonomy?

Any idea if a scrubber pack with an autonomy of 6 hours can be reused
safely after a dive of 2-3 hours or if is it necessary to replace it
systematicly?

Thanks for your help

Frederic
