摘要： A separating column (12) for hippuric acid analysis is filled with a filler in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to a silica matrix. By using such a filler for the separating column (12) in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to the silica matrix, hippuric acid, o-methyl hippuric acid, m-methyl hippuric acid, p-methyl hippuric acid, and mandelic acid can be separated without using a mobile phase containing cyclodextrin.

摘要： A liquid delivery device includes a liquid delivery pump that sucks a mobile phase, which is liquid, from a mobile phase container containing the mobile phase through a suction pipe whose end is immersed in the mobile phase in the mobile phase container, and feeds the mobile phase, and at least one dissolved substance removal filter that is provided at a position upstream of the liquid delivery pump on a path through which the mobile phase flows and is filled with a filler having the property of adsorbing a dissolved substance in the mobile phase.

摘要： A preparative chromatograph for collecting target components in a sample temporally separated in a column of a chromatograph in respective preparative containers is provided with: a detection unit having a flow cell accommodated in a housing and a detector for detecting a component that passes through the flow cell; a first pipe that connects the column and an inlet end of the flow cell; a flow path switching unit accommodated in the housing and configured to selectively flow the components that passed through the flow cell through a preparative flow path that is a flow path connected to the preparative containers or a waste liquid flow path; and a second pipe accommodated in the housing and connecting an outlet end of the flow cell and the flow path switching unit.
