A surface acoustic wave (SAW) propagating on 36 deg. rotated Y-cut, X-propagating LiTaO<sub>3</sub> is a pseudo mode with a shear horizontal polarized displacement (SH-SAW). Recent reports have shown that liquid-phase sensor using SH-SAW device can detect electrical properties of liquid with high sensitivity. This paper describes a novel technique for identifying the differences of ionic solutions by use of the SH-SAW sensor in a liquid flow system. The identification principle is based on the time responses of the samples obtained from the flow system. Several kinds of ionic solutions, such as aqueous solutions of HCl, LiCl, etc., are measured and observed evident difference in transient. Using pattern matching based on the transient responses, unknown samples are distinguished perfectly. Moreover, not only kind of ion but also the conductivity and the molar concentration are determined.
