摘要：
Disclosed are a method of determining the amount of the substances or ions contained in an ionic solution or a non-deionized solution by measuring the frequency of a one side barrier-covered crystal oscillator comprising a crystal oscillator 1,2a,2b, a barrier 6 to cover over one of the electrodes 2b of the crystal oscillator through a predetermined insulative space 5 so as to prevent the ionic solution or the non-deionized solution from permeating therethrough and an adsorption film 7 cast on the other electrode 2a of the crystal oscillator, in situ in the state that the one side barrier-covered crystal oscillator is dipped in the ionic solution or the non-deionized solution, and the one side barrier-covered crystal oscillator used therefor.
