Abstract
Method and apparatus for determination of the concentration of a component in a solution, such as ethyl alcohol in gasohol, acetic acid in hexane-acetic acid solution, or the like. Such determination is made with ease and accuracy based on a rate of pressure change caused in a closed container due to mass transfer occurring between two liquids through porous material.
