A gas extraction apparatus provides for reliable and accurate extraction of gases dissolved in fluids and routing the extracted gas to an analytical instrument. An extraction module comprises one or more fluorosilicone membranes molded into the shape of a flattened disk. The membranes are retained in a housing in a spaced apart relationship. The membrane is permeable to target gas(es), but not to the fluid. Porous support members support the membranes and prevent damage to them and the housing defines separate fluid flow paths for the fluid and the gas extracted from it.

The invention claimed is: 1. Apparatus for extracting gas from fluid, comprising:a housing defining a fluid pathway and a gas pathway that is isolated from the fluid pathway, said housing having an inlet into the fluid pathway and an outlet from the fluid pathway, and an inlet into the gas pathway and an outlet from the gas pathway;at least one separation membrane in the housing separating the fluid pathway from the gas pathway, the at least one separation membrane comprising a fluorosilicone member that is substantially impermeable to the fluid and permeable to the gas, said separation membrane having a first side facing the fluid pathway and a second side facing the gas pathway and wherein the at least one separation membrane defines a generally flattened disk that is thicker at peripheral portion thereof and thinner at the center of the flattened disk;a porous membrane support facing the first side of the separation membrane; andwherein the fluid pathway includes the first side of the at least one membrane.
