A system for humidifying oxygen for low-flow oxygen therapy includes a volume-adaptable water reservoir that contains, in addition to water, a water-vapor-permeable membrane.
A hybrid cooler/dryer that conditions a sample gas includes a heat exchanger, a condensate-removal device, and a membrane dryer. In some embodiments, the hybrid cooler/dryer also includes passive cooling, as embodied by an air amplifier and heat sink, or a length of tubing that exposes the sample gas to ambient temperature. The hybrid cooler/dryer requires no electrical power.

A method for drying a gas sample comprises flowing purge gas over the exterior of tubes of a perfluorosulfonic acid membrane and flowing the gas sample through interior of tubes, wherein the drying operation is conducted under deep vacuum and with the purge gas flowing at a rate that is typically less than that of the gas sample being dried.
A portable sampling system includes a heated probe, an input/output (“I/O”) system, and one membrane dryer in the form of a conduit that couples the probe to the I/O system. The dryer has purge gas flowing over the drying membrane and a gas sample flowing through the drying membrane, which is in the form of tubes of a perfluorosulfonic acid material, and wherein the dryer is operated in some embodiments under deep vacuum and with the purge gas flowing at a rate that is typically less than that of the gas sample being dried.
A membrane gas dryer includes an upstream fitting assembly, a downstream fitting assembly, a purge tube, and a sample element. The upstream fitting assembly and the downstream fitting assembly include fitting bodies and barrier sleeves. The fitting bodies and the barrier sleeves form purge plenums that are in fluid communication with the purge tube. Sealing interfaces on the fitting bodies maintain fluid-tight seals around the purge plenums as the barrier sleeves rotate about fitting bodies. The sample element includes a water-permeable membrane and passes inside the purge tube such that moisture in a sample gas flowing in a downstream direction through the sample element between the fitting body to the downstream fitting body passes moisture through the water-permeable membrane and into a purge gas flowing in the purge tube in one of an upstream direction or a downstream direction between the purge plenums.

SEPARATING PARTICULATE-CONTAINING GAS FLOW INTO PARTICULATE AND NON-PARTICULATE FLOW PORTIONS
In accordance with one embodiment of the present invention, an apparatus for separating a particulate-containing gas flow into particulate and substantially non-p articulate flow portions is provided. The apparatus comprises a sample gas inlet, a radial separating ring, a separation draw, a separated gas outlet, a bypass eductor, and a bypass gas outlet. The radial separating ring comprises a separating ring gap defined between an inlet ring orifice and an outlet ring orifice, and is positioned such that a sample gas flow moving downstream from the sample gas inlet through the bypass eductor to the bypass gas outlet passes across the separating ring gap. The radial separating ring is configured such that the inlet ring orifice and the outlet ring orifice are relatively large, in relation to the size of the separating ring gap, and are positioned in close proximity to each other along the direction of the sample gas flow. The separation draw is configured to permit a substantially non-particulate portion of a sample gas flow moving across the separating ring gap to be drawn from the radial separating ring to the separated gas outlet.
