Abstract
Description
図1は、実施形態に係るガス測定器の一例を示す概要図である。図1に示されるガス測定器1は、サンプルガス100から対象ガスを検出する機器である。サンプルガス100は、大気中のガスであり、主に窒素(N2)ガス、酸素(O2)ガス及び希ガスから選択された少なくとも一種のガスを含む。希ガスは、例えばヘリウム(He)及びネオン(Ne)である。サンプルガス100は、水蒸気又は水素(H2)ガスを含んでもよい。なお、サンプルガス100は、閉空間から取得されてもよい。
真空ポンプ5が動作することにより、チャンバ3の内部空間が減圧される。これにより、サンプルガス100が吸気配管6に引き込まれる。引き込まれたサンプルガス100は、第一フィルタ8を通過する。このとき、サンプルガス100に含まれる酸素ガス及び水蒸気が第一フィルタ8の多孔性金属錯体8bによって除去される。続いて、サンプルガス100は、第二フィルタ9を通過する。このとき、サンプルガス100に含まれる窒素ガス及び希ガスが第二フィルタ9の多孔性金属錯体9bによって除去される。これにより、サンプルガス100中の大気の主成分が除去され、サンプルガス100において対象ガスの濃度が上昇する。チャンバ3内において濃縮された対象ガスは、ガスセンサ2によって検出される。
ガス測定器1によれば、フィルタ7によって、大気中のサンプルガス100に含まれる対象ガスが吸着されることなく、サンプルガス100から窒素ガス、酸素ガス又は希ガスが除去され、ガスセンサ2によってサンプルガス100から対象ガスが検出される。窒素ガス、酸素ガス又は希ガスは、大気中に多く含まれるとともにガスセンサ2の検出感度を低下させる要因となる。大気中の主成分ガスがフィルタ7によって除去されることにより、検出感度を低下させるガスが除去されるとともに、対象ガスが相対的に濃縮される。よって、ガス測定器1は、大気中の対象ガスの検出精度を向上できる。また、ガス測定器1によれば、対象ガスを相対的に濃縮するため、対象ガスのガス種ごとに専用の濃縮器などを用意する必要がなく、簡易的に対象ガスの検知精度を高めることができる。つまり、ガス測定器1は、ガスセンサの種類に関わらない汎用的に使用可能な濃縮機能を提供できる。
以上、種々の例示的実施形態について説明してきたが、上記の例示的実施形態に限定されることなく、様々な省略、置換、及び変更がなされてもよい。
