description	To prevent gas to be supplied into a detector from being contaminated by gas having been supplied into the detector.SOLUTION: The present invention includes: a joining unit (250) for causing a plurality of cells (110, 120, and 130) to join together, the cells discharging detection gas; a supply line (210) for a first carrier gas including no target components; a detector for detecting the detection gas sent through the joining unit (250). There are valves (421, 422, 423) for switching the flow passage of the detection gas between the cells (110, 120, 130) and the joining unit (250).SELECTED DRAWING: Figure 1 【課題】先に検出器に供給される気体によって、後に検出器に供給される気体が汚染されることを防ぐ。【解決手段】検出ガスを排出する複数のセル（１１０，１２０，１３０）のそれぞれを合流させる結合部（２５０）と、標的成分を含んでいない第１キャリアガスの供給ライン（２１０）と、結合部（２５０）を経由して送られた、検出ガスを検出する検出器と、を備え、セル（１１０，１２０，１３０）と結合部（２５０）との間のそれぞれに、検出ガスの流路を切り替えるバルブ（４２１，４２２，４２３）が設けられている。【選択図】図１
