Abstract
A method is provided that allows the sulfur component concentration in gasoline to be estimated to high precision. The measuring method of the disclosure is a method of measuring the concentration of sulfur components in gasoline that contains sulfur components and aromatic components. The measuring method of the disclosure comprises: (A1) removing a portion of the gasoline by gasification to lower the proportion of the aromatic component concentration with respect to the sulfur component concentration in the gasoline, (A2) measuring values related to the refractive index of the gasoline, and (A3) measuring the sulfur component concentration in the gasoline based on the values related to the refractive index.
