Abstract
Device for recovering a material to be measured comprising a reservoir filled with a sample holding material impregnated with a sample liquid in which a material to be measured is dissolved and an adsorbing column for adsorbing the material to be measured, wherein the reservoir and the adsorbing column are communicated by a straight pipe, and further communicated with a recovery vessel via a recovery pipe branched out the straight pipe. Accordingly, operations of opening/closing or switching a first valve provided on the in-flow side of the reservoir, a second valve provided on the out-flow side of the adsorbing column, and a third valve provided to a vent hole to the atmosphere in the recovery vessel, make it possible to recover the material to be measured without depositing the material on the valves.
