Abstract
A method for analyzing gas dissolved within a fluid filled asset includes extracting the fluid from the fluid filled asset, circulating the fluid though a first fluid loop, and passing the extracted fluid along a first side of a gas permeable membrane. Gas is extracted from a second side of the gas permeable membrane and the extracted gas is circulated through a second fluid loop. The first fluid loop and the second fluid loop are separated by the gas permeable membrane. The method further includes controlling a pressure differential across the gas permeable membrane to a predetermined pressure differential and providing the extracted gas to a gas analysis unit located within the second fluid loop. The chemical makeup of the extracted gas is periodically determined using the gas analysis unit.
