| Abstract: | A resonance sensor employing lithium tetraborate crystal as piezoelectric material is developed.This sensor has sensitive frequency response to conductivity and permittivity of the liquids.Microcontent water in organic solvents is rapidly determined by the sensor.The determination limits for water in dioxane,ethyl acetate,n-amyl alcohol are 0.5,0.7 and 1.7 mg/L,respectively. |
