Abstract
A tubular membrane extractor column is connected to an oil filled electrical component such as a transformer. Fault gases dissolved in the transformer oil are extracted from the oil in the separator and are isolated in a second phase. Oil and second phase gas are circulated in separate flow paths until equilibrium is reached. Equilibrated gas is routed to a gas chromatograph or other analytical instrument requiring controlled fluid flow, and which incorporates a manifold assembly that eliminates the need for many of the external fittings and connections required in the instrument. A manifold block has plural fluid flow paths formed therethrough to route fluids to selected components. A collar mates to the block and adapts to a rotary injection valve to provide the continued fluid paths from the block to the injector valve and the other components of the instrument.
