Summary:To quickly and inexpensively carry out the pretreatment of an analysis sample that includes suspended solids as does an emulsion or a suspension.SOLUTION: Provided is an analysis sample pretreatment device 1 for obtaining a clarified liquid with suspended solids removed from an analysis sample. The analysis sample pretreatment device 1 comprises a cell 10 for accommodating the analysis sample, and a cell holder 20 with at least a portion of housing opened in order for the cell 10 to be mounted. The cell holder 20 includes an ultrasonic vibrator 202 and an ultrasonic reflection plate 206 arranged to a plane pair facing each other across the cell 10 mounted in the inside, and the cell 10 includes a first opening 101 through which the analysis sample flows in, a second opening 102 through which the clarified liquid flows out, and a third opening 103 for ejecting suspended solids. While the cell 10 is mounted to the cell holder 20, the first opening 101 is located at a position lower in the vertical direction than the upper end of the ultrasonic vibrator 202 or a position higher in the vertical direction than the lower end of the ultrasonic vibrator 202.SELECTED DRAWING: Figure 3 【課題】乳濁液や懸濁液のように、濁質を含む分析試料の前処理を、速やか且つ低コストで実施する。【解決手段】分析試料から濁質を除去した清澄液を得る分析試料前処理装置１であって、分析試料を収容するためのセル１０と、セル１０を装着するために筐体の少なくとも一部が開口されたセルホルダ２０と、を備え、セルホルダ２０は、内部に装着されたセル１０を挟んで対向する平面対に配置された超音波振動子２０２及び超音波反射板２０６を有し、セル１０は、分析試料を流入する第１開口部１０１、清澄液を流出する第２開口部１０２、及び濁質を排出する第３開口部１０３を有し、セル１０をセルホルダ２０に装着した状態において、第１開口部１０１は、超音波振動子２０２の上端よりも鉛直方向で低い位置、または超音波振動子２０２の下端よりも鉛直方向で高い位置に設けられていることを特徴とする、分析試料前処理装置１。【選択図】図３
