Abstract
A gas dryer cartridge for removing the moisture from a sample gas stream prior to the application thereof to a metabolic measuring instrument. A dryer housing having an inlet and an outlet is partitioned into a first, gas drying chamber containing a desiccant and a second, liquid collecting chamber containing an absorbent liquid retaining element. The volume of the liquid collecting chamber is made sufficiently large that it can contain the liquid produced in the event that the desiccant is liquefied as a result of prolonged use. The liquid retaining element prevents the collected liquid from being swept up in the gas stream during the removal or replacement of the cartridge.
