Claim:
1. A liquid chromatography device comprising: an adsorption portion that adsorbs one or more analysis components in a specimen; an analysis device that analyzes an analysis component eluted by an eluent; a main feeding device that feeds a first eluent to the adsorption portion, the first eluent eluting an analysis component; a feeding channel in fluid communication with the main feeding device and the adsorption portion; a first retention channel that retains a second eluent, the second eluent differing from the first eluent; an auxiliary feeding device that feeds the second eluent to the first retention channel; and a first switching device that switches the feeding channel to either a first channel or a second channel, the first channel allowing the first eluent to flow from the main feeding device to the adsorption portion, and the second channel allowing the second eluent to flow from the first retention channel to the adsorption portion, wherein the main feeding device serves as a high pressure pump, and wherein the auxiliary feeding device serves as a low pressure pump.
