Abstract
Provided is a liquid chromatography apparatus for fast measuring, and more particularly, a liquid chromatography apparatus which includes a first column and a second column having different component separations for an interest component within a sample and makes components primarily separated in the first column be secondarily separated in the second column of a first channel unit before a switching valve is switched, makes the components primarily separated in the first column be continuously discharged through a second channel unit after the switching valve is switched, thereby improving the component separation and achieving the fast measuring.
