Abstract
A gas permeable probe for use in the analysis of absorbed gases in liquids, notably in the blood, by mass spectroscopy, comprises a flexible plastics capillary tube fitted at one end with a plug of porous material and covered with a protective layer of polymeric material. The gas permeability of the porous plug is substantially less than that of the polymeric layer so that it is the plug which defines the gas flow from the liquid under test into the tube when the tube is evacuated.
