Abstract:
1. A liquid chromatography apparatus comprising: a column holding a column package; and one or plural eluting solution holding parts holding an eluting solution to be supplied to the column; wherein the liquid chromatography apparatus further comprises a dissolved oxygen density adjusting means for maintaining a density of a dissolved oxygen in the eluting solution to be supplied to the column constant, the liquid chromatography apparatus further comprising: a deaerator for deaerating the eluting solution during supply of the eluting solution from the eluting solution holding part to the column and having a gas permeable film and a decompression space; wherein the dissolved oxygen density adjusting means has a temperature measuring means for directly or indirectly measuring the temperature of the eluting solution to be supplied to the column and is configured so as to adjust a density of a dissolved oxygen in the eluting solution by adjusting a degree of decompression in the decompression space based on the measurement result by the temperature measuring means.
