ABSTRACT:
An apparatus for determining the amount of any chemical substance exhibiting a surface activity. A monomolecule film including a surface active substance exhibiting a surface activity is formed on a surface of a surface active substance solution in which the surface active substance is dissolved. Subsequently, a surface pressure of the monomolecule film is measured in order to find a concentration of the surface active substance where a content of the surface active substance is defined by the concentration of the surface active substance and the amount of the solution.
