Abstract
PURPOSE: To perform the measurement of gas density at high response and with ease with a simple constitution by letting the gas to be examined be absorbed in the absorbing liquid in the circulating route formed by a gas permeable membrane and measuring pH value.
CONSTITUTION: The sodium bicarbonate solution of the specified concentration in a bicarbonate ion liquid vessel 6 is passed through the circulating line formed by a tube 5 of a gas permeable membrane of silicone, Teflon or the like of spiral form, the flow cell 8 provided in a pH electrode 1, etc. within the inspecting gas body 4 and is returned into the vessel 6 by a pump 7. During this time, the solution in the specimen responds at a high speed with the sodium bicarbonate solution of the absorbing solution owing to its large contact area with said solution and stirring effect by the spiral form and becomes equilibrium. Hence, if the pH value of the sodium dichromate solution is measured with the electrode 1, high input impedance voltmeter 9, etc., the carbonic acid gas density in the specimen may be measured readily at high response. If a Teflon gas permeating tube is used with an aqueous ammonium chloride solution as an absorbing solution, the density of ammonia is measured.
