Abstract
It is possible to reduce a burden on a user in performing a spectroscopic analysis of a liquid sample. There is provided an analysis cell that is detachable and replaceable with respect to an analysis unit and accommodates a liquid sample, the analysis cell including a first wall surface pair that is made of a material transmitting a light, and a second wall surface pair for propagating an ultrasonic wave to the accommodated liquid sample, in which a first wall surface and a second wall surface forming the second wall surface pair and facing each other, are formed of materials having different acoustic impedances.
