<p>PROBLEM TO BE SOLVED: To provide a gas concentration device securely desorbing even when a high boiling point VOC is adsorbed by an adsorption rotor, consuming only a small amount of energy and provided with a high concentration factor. SOLUTION: The adsorption rotor 1 is divided into an adsorption zone 2, a first desorption zone 3 and a second desorption zone 4 formed in the above order in its rotating direction, and air heated by a first heater 6 is passed through the first desorption zone 3, and also the air passed through the first desorption zone 3 is passed to the second desorption zone 4 through a second heater 7.</p> |
