gas analysis system:μGAS）を開発した．水溶性ガスの簡易で高感度な分析装置はこれまでなかったが，マイクロチャネルを利用したスクラバーを開発し，さらに送液やリアクター，検出器，校正用ガス発生など周辺技術も合わせて確立し，片手で持ち運べる連続分析装置をつくりあげた．マイクロチャネルスクラバーにて目的成分を吸収溶液に捕集するが，従来のインピンジャーに比べると20000倍もの捕集濃縮効果を持つため，高い感度と高い時間分解能の両立がはかれた．これまで開発したμGASの対象物質は，SO_2, H_2S, CH_3SH, COS, NO, NO_2, HONO, HCHO, NH_3などであり，いずれもppbvオーダーの濃度領域における連続分析を可能にした. これらのμGAS装置により，都市大気，森林大気，火山ガス，土壌からの発生ガスなどの解析を行い，局所的な汚染の提示や大気化学の解明に役立ててきた．また，NOは水に溶解しにくいが，反応系を工夫し呼気中のNOの分析に成功した．さらに，チャネル型のスクラバーについて，ガス捕集をシミュレーションする表計算ソフトを開発し，新規なスクラバーの設計・開発に役立ててきた．そのひとつの応用として，気体成分のHCHOをチャネル型スクラバーで取り除いたところ，残った粒子状物質にHCHOが存在することを見いだし，PM2.5など粒子状物質へのHCHOの分配の推移を明らかにした.","subitem_description_type":"Other"}]},"item_16_description_77":{"attribute_name":"URL","attribute_value_mlt":[{"subitem_description":"https://www.jstage.jst.go.jp/article/bunsekikagaku/63/11/63_873/_article/-char/ja/","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会
