1. A chemical sensor system comprising:
a first chemical sensor;
a second chemical sensor unit; and
a first sample atmosphere tank located between the first chemical sensor and the second chemical sensor unit, and including
an air supply mechanism that executes a first operation of supplying a sample atmosphere from the first chemical sensor to the first sample atmosphere tank, a second operation of supplying the sample atmosphere from the first sample atmosphere tank to the second chemical sensor unit, and a third operation of discharging the sample atmosphere in the first sample atmosphere tank,
wherein the second chemical sensor unit comprises: a mechanism that exposes the sample atmosphere to a sensing solution; and a second chemical sensor that responds to a target substance contained in the sensing solution to which the sample atmosphere is exposed, wherein the first chemical sensor is a gas phase sensor and the second chemical sensor is a liquid phase sensor.
