An LC device for analyzing a sample liquid containing an objective substance to be measured, the LC device being provided with: an EO pump (21) for conveying a mobile phase solvent; a separation column (5) positioned downstream from the EO pump (21) and holding filler material therein; a detector (7) that is positioned downstream from the separation column (5), and analyzes the objective substance outputted from the separation column (5); and a pressure adjustment mechanism (80) that is positioned downstream from the EO pump (21) and adjusts the fluid pressure of the mobile phase solvent stored in a second reservoir (22) provided downstream from the EO pump (21), or the fluid pressure of the mobile phase solvent stored in a channel. |
