ANALYSIS METHOD OF SILANE-COUPLING AGENT AQUEOUS SOLUTION, AND MANUFACTURING METHOD OF HUMIDITY SENSOR ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an analysis method of a silane-coupling agent aqueous solution capable of qualitatively and quantitatively analyzing a hydrolyzed product of a silane-coupling agent and a condensate thereof. SOLUTION: This analysis method of the silane-coupling agent aqueous solution includes a column passing process for passing a sample, which is obtained by dissolving the silane-coupling agent in an acid aqueous solution, through a column filled with an inert porous solid, an ultraviolet/visible absorption analyzing process for successively analyzing the sample passed through the column by an ultraviolet/visible absorption spectrum analysis method and a mass-analysis process.
