Abstract: To prevent lowering of sensitivity of a flow cell based on total reflection of light at an outer face of a glass capillary at a joint part with a pipe, the flow cell includes, at joint parts with a pipe 605 to introduce solution to a glass capillary 601 and with a pipe to discharge solution from the capillary, an inorganic material layer 602 that reflects measurement light to modify the outer face of the glass capillary as well as a reinforcement layer 711 to modify the surface thereof.

Abstract: A detector for liquid chromatography has light sources that generate light in an ultraviolet region and in a near-infrared region; a flow cell, through which sample liquid flows; an optical system to let light generated from the light sources become incident on the flow cell concurrently; a detection element that detects light in the ultraviolet region that passes through the flow cell; a detection element that detects light in the near-infrared region that passes through the flow cell; and an arithmetic operation part that performs arithmetic operation of a first signal value obtained from the detection element and of a second signal value obtained from the detection element. The arithmetic operation part combines the first signal value and the second signal value to calculate a signal value with a reduced baseline fluctuation resulting from a mobile phase during a gradient analysis.
