Patent ID: 7708807

Claim:
A device for recovering a material to be measured for dissolving the material in a solvent held by a reservoir to impregnate the solvent to an adsorbing column, eluting the adsorbed material with an eluant, and recovering the material in a recovery vessel, the device comprising: a straight pipe communicating an out-flow side of the reservoir with an in-flow side of the adsorbing column; and a branch node, branching at a middle of the straight pipe, connectable to a recovery pipe communicated with the recovery vessel a first valve configured to open and close an in-flow side of the reservoir to feed the solvent therein for dissolving the material to be measured; a second valve on an out-flow side of the adsorbing column configured to switch between a discharge of the solvent and a supply of the eluant for recovering the material to be measured adsorbed in the adsorbing column; the recovery vessel being provided to the recovery pipe; a vent hole being communicated with the recovery vessel; and a third valve configure to open and close the vent hole.
