so, from a unit marketing standpoint, you are saying you'd rather see cannister volume, yes? From a performance standpoint then, it would be beneficial to quote approximate weight of absorbant. (for example, 'our 2L cannister holds 1.5kg of absorbant'...or something to that effect.)
reason I'm trying to sort through this is that I have spent a good deal of time working out the theoretical bedlife calculations proposed in Nuckols et al for both sodasorb and sofnolime based ona fixed set of environmental and metabolic variables and am working out a table that might aid in determining a basic level of scrubber performance. This excersize has provided some very useful and interesting data that we'll be publishing shortly. We're a bit up in the air on whether to present the data with Kg or L.

The cannister volume is the only fixed item.
That is the only thing that is set by the manufacturer.
The moment you quote weight you are 'assuming' the density of a product you do not control.
Also: I fill by volume. By all means quote the 'expected' weight but do any of us measure out 3.2Kgs of 'sorb and try to fit that in the can?
