Abstract: Provided is a method for accurately quantifying a chemical substance contained in a sample solution at a significantly low concentration of not more than 1×10−8 M. A measurement system used for the method includes a counter electrode 13, a first reference electrode 12, a first working electrode 11a, a second working electrode 11b, a second reference electrode 14 and a gel-coated electrode 15. The gel-coated electrode 15 is electrically equivalent to the second working electrode 11b. The gel-coated electrode 15 comprises an electrode body 31 and a gel 34. The surface of the electrode body 31 is coated with the gel 34. The gel 34 contains a standard electrolyte and an ionic liquid. The gel 34 contains no water. The ionic liquid is hydrophobic and nonvolatile. The ionic liquid is composed of a cation and an anion. The standard electrolyte is composed of the cation and a halide ion.

Abstract: Provided is a method for accurately quantifying a chemical substance contained in a sample solution at a significantly low concentration of not more than 1×10−8M. First, prepared is a measurement system including a counter electrode 13, a first reference electrode 12, a first working electrode 11a, a second working electrode 11b and a second reference electrode 14. Second, voltages of V1 volts and V2 volts (V1>V2) are applied to the first working electrode 11a and the second working electrode 11b, respectively. Third, a voltage difference ΔE between the second working electrode 11b and the second reference electrode 14 is measured. Finally, the concentration of the chemical substance is calculated on the basis of the voltage difference ΔE.
