EVAPORATIVE CONCENTRATION MECHANISM, ANALYSIS DEVICE PROVIDED WITH SAME, AND CONTROL METHOD FOR EVAPORATIVE CONCENTRATION MECHANISM

An evaporative concentration mechanism is achieved, which accurately evaporates and concentrates a small quantity of a sample liquid for a short period of time, regardless of the composition of the sample liquid or the surrounding environmental conditions.An evaporative concentration mechanism includes a container 1 that accommodates a sample liquid; a heating unit 3 that heats the container; a liquid level sensor 6 that detects a liquid level height of the sample liquid accommodated in the container; and a control unit 5 that controls a temperature of the heating unit, in which the control unit 5 controls the temperature of the heating unit based on a liquid level of the sample liquid detected by the liquid level sensor 6. Accordingly, a small quantity of a sample liquid can be accurately evaporated and concentrated for a short period of time, regardless of the composition of the sample liquid or the surrounding environmental conditions.
