The present invention provides a plasma spectrochemical analysis method that can be carried out easily and achieves high analytical sensitivity, and includes: a step of concentrating an analyte in a sample in the vicinity of at least one of a pair of electrodes by applying a voltage to the pair of electrodes in the presence of the sample; and a step of generating plasma by applying a voltage to the pair of electrodes and detecting light emitted from the analyte excited by the plasma.

A mixing apparatus includes: a mixing container with a discharge port for discharging mixed liquid; a filter paper covering the discharge port to temporarily retain the liquid; a receiving unit with a waste liquid collecting portion for receiving a first liquid discharged from the discharge port through the filter paper, and a measuring portion for receiving a second liquid subjected to treatment different from treatment for the first liquid; and an operation portion for enabling selection between a first receiving state in which the waste liquid collecting portion receives the first liquid and a second receiving state in which the measuring portion receives the second liquid, and also for controlling the movement of the first liquid or the second liquid.
