Apparatus preparing samples to be supplied to an ion mobility sensor

An apparatus comprising:

• a unit of preparing a sample to be supplied to an ion mobility sensor;
• and
• a control unit including a function for controlling the unit of preparing,
• wherein the unit of preparing includes a concentration adjusting mechanism changing a concentration of a first constituent included in the sample, and
• the control unit includes a function of acquiring a measurement result of the ion mobility sensor and a function of controlling the concentration adjusting mechanism in a direction in which the measurement result improves, and
• the function for controlling the concentration adjusting mechanism includes:
• a function of preliminarily analyzing measurement results obtained by controlling the concentration adjusting mechanism so as to change the concentration of the first constituent in stages and selecting a chemical substance candidate included in the first constituent;
• and
• a function of accessing a database of a plurality of chemical substances that are to be measured by the ion mobility sensor and includes data on concentrations of each of the plurality of chemical substances that are suited to detection by the ion mobility sensor to acquire a detection concentration suited to detecting the chemical substance candidate and controlling the concentration adjusting mechanism so that a concentration of the first constituent included in the sample becomes the detection concentration.
