The present invention relates to a liquid chromatography apparatus X, which is provided with a deaerator. The liquid chromatography apparatus X is further provided with a dissolved oxygen density adjusting means for maintaining a density of dissolved oxygen in an eluting solution to be supplied to a columnconstant. Preferably, the dissolved oxygen density adjusting means is configured so as to adjust the density of the dissolved oxygen in the eluting solution by adjusting a degree of decompression in a decompression space of the deaeratorbased on a measurement result by temperature measurement meansA,B, andC for measuring the temperature of the eluting solution.
