A gas-liquid separator apparatus and device, particularly for use in connection with medical gas analyses, such as capnography, is provided. The separation chamber tapers in a direction from the blow down port to the dry gas outlet port providing increased surface area in the lower portion of the separation chamber for providing capillary volumes or regions. A solid body is disposed in the separation chamber to provide a surface of the capillary volumes and to decrease the effective volume of the separation chamber. The body can be used to occlude the dry gas outlet port upon tipping of the separation chamber at greater than a predetermined angle. A number of internal fins extend inwardly from the side wall and bottom surface into the separation chamber to form capillary volumes in cooperation with the side wall, bottom surface and/or solid body.

In a system for analyzing samples of an exhaled mixture of gas and liquid, a fast-response apparatus usable for obtaining a substantially dry gas sample from a sample of said mixture of gas and liquid, comprising: a microvolume separation chamber defined by a first end surface, a second end surface, and a side wall, said side wall defining the cross-sectional area of said separation chamber, at least a portion of said sidewall being free from projections extending inward into said separation chamber; inlet port means for introducing a sample of said mixture of gas and liquid into said separation chamber in a radial direction towards the center of said separation chamber; first outlet port means for removing substantially dry gas for said analyzing, said outlet port means being substantially adjacent to said first end surface; and second outlet port means for removing a waste mixture of gas and liquid from said separation chamber for dispersal, said second outlet port means being substantially adjacent to said second end surface; at least one fin extending inward from said sidewall into said separation chamber wherein the cross-sectional area of said separation chamber adjacent to said first end surface is less than the cross-sectional area of said separation chamber adjacent to said second end surface.
