HEAVY METAL ANALYZER AND HEAVY METAL ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a heavy metal analyzer which continuously carries out cleaning of a measuring sample, extraction of a heavy metal from the measuring sample, and analysis and measurement of the heavy metal, and to provide a heavy metal analysis method.SOLUTION: A heavy metal analyzer comprises a heavy metal extraction unit 11, a heavy metal adsorption unit 12 and an elution unit 13. In the heavy metal extraction unit 11, a fixed amount of extraction liquid 17a is circulated to pass the extraction liquid through a column 16 filled with a measuring sample 16a containing heavy metals, thereby the measuring sample is cleaned and the heavy metals are extracted into the extraction liquid. The heavy metal adsorption unit 12 selectively adsorbs a heavy metal to be measured from the extraction liquid in which the heavy metals have been extracted by the heavy metal extraction unit. The elution unit 13 eludes the heavy metal adsorbed by the heavy metal adsorption unit using an eluent 18. The heavy metal extraction unit and the heavy metal adsorption unit are connected to each other by a first flow passage 19, the elution unit and the heavy metal adsorption unit are connected to each other by a second flow passage 21, and the heavy metal adsorption unit is connected to a measuring unit 14 which measures the eluded heavy metal contained in the eluent, by a third flow passage 22.
