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 ofa one side barrier-covered crystal oscillator comprising a crystal oscillator 1,2a,2b, abarrier 6 to cover over one of the electrodes 2b of the crystal oscillator through apredetermined insulative space 5 so as to prevent the ionic solution or the non-deionizedsolution from permeating therethrough and an adsorption film 7 cast on the otherelectrode 2a of the crystal oscillator, in situ in the state that the one side barrier-coveredcrystal oscillator is dipped in the ionic solution or the non-deionized solution, and the oneside barrier-covered crystal oscillator used therefor.
