Abstract
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.
