Abstract: An apparatus for permeability analysis which transmits a testing fluid to the tubular specimen and measures the volume of the testing fluid permeating through the tubular specimen. The apparatus for permeability analysis has a tubular specimen, a cylindrical frame, a carrier gas flow inlet leading from the outside of the cylindrical frame to the inside of the cylindrical frame, a carrier gas flow outlet leading from the inside of the cylindrical frame to the outside of the cylindrical frame, a detection device, and a pump. One end of the tubular specimen and the other end of the tubular specimen are connected to each other via the pump. The apparatus for permeability analysis circulates a testing fluid through the tubular specimen continuously or intermittently by means of a pump, conveys the permeate to the detection device by means of the flow of the carrier gas, and then measures the permeate.
