Abstract

See full text

The object of the invention is to perform, rapidly and at a low cost, a pretreatment of an analysis sample containing a turbid substance. Provided is an analysis sample pretreatment apparatus in which a clarified liquid is obtained by removing a turbid substance from an analysis sample. The analysis sample pretreatment apparatus includes a cell configured to store the analysis sample, and a cell holder in which at least a part of a housing is opened to mount the cell. The cell holder includes an ultrasonic wave transducer and an ultrasonic wave reflection plate that are disposed on facing plane pairs while sandwiching the cell mounted inside the cell holder. The cell includes a first opening unit from which the analysis sample flows in, a second opening unit from which the clarified liquid flows out, and a third opening unit from which the turbid substance is discharged. In a state where the cell is mounted in the cell holder, the first opening unit is provided at a position lower than an upper end of the ultrasonic wave transducer in a vertical direction, or at a position higher than a lower end of the ultrasonic wave transducer in the vertical direction.
