PROBLEM TO BE SOLVED: To provide a reactive gas detection device capable of measuring accurately the concentration even if the gas concentration is low, and measuring by a simple operation with a simple constitution, and especially usable suitably for measurement of a gas component having high reactivity and the low concentration such as formaldehyde measurement, when measuring a gas component having high reactivity. SOLUTION: This device is equipped with a concentrator 2 for concentrating a reactive gas in gas to be measured, and a detector 6 for detecting the reactive gas concentrated by the concentrator 2. The concentrator 2 is equipped with an adsorbent for adsorbing the reactive gas in the gas to be measured and desorbing the reactive gas by heating without generating a reaction, and a heater 13 for heating the adsorbent. The detector 6 is equipped with a separation column 18 and a semiconductor gas sensor 20. COPYRIGHT: (C)2006,JPO&NCIPI
