PROBLEM TO BE SOLVED: To provide high-speed liquid chromatograph allowing recycling with only a part of components of a specimen taken as an object without performing a separate recovery operation. SOLUTION: A column switch mechanism is incorporated into this high-speed liquid chromatograph used for performing recycle analysis to switch recycling object components to a second column. Thereafter, the object components switched to the second column are passed through the second column a plurality of times by using a second moving phase. COPYRIGHT: (C)2011,JPO&INPIT
