Liquid chromatograph including spectroscopic analysis units

Abstract

A liquid chromatograph including a spectroscopic analysis unit () that performs spectroscopic analysis by irradiating a flow cell () through which an eluent eluted from a column () flows with light is provided with a cell information reading unit () that is provided in the spectroscopic analysis unit and accesses a storage device () attached to the flow cell to acquire cell information that is information unique to a type or an individual of the flow cell; a wavelength check control unit () that causes the spectroscopic analysis unit to execute wavelength check; a wavelength check information storage unit () in which a result of the wavelength check is stored in association with the cell information acquired at a time of executing the wavelength check; and a system check report creation unit () that creates a system check report in which the result of the wavelength check and the cell information acquired at the time of executing the wavelength check are described by referring to the wavelength check information storage unit. This makes it possible to sufficiently secure the reliability of the analysis result.
