Abstract:
Disclosed are a measurement method and a measurement apparatus both of which can measure the content of water or an organic acid in a polar organic solvent with high accuracy even when water or the organic acid is contained in the polar organic solvent at a low content. The content of water or an organic acid in a polar organic solvent can be measured by using, as a work electrode, an ISFET electrode in which a thin film comprising an oxide or nitride of a metal or metalloid element belonging to Groups 3 to 15 is formed on a gate.
