FlexMat, EarlyView.Abstract Salicylic acid (SA), a widely distributed environmental pollutant, requires accurate detection for effective water quality monitoring and ecological protection. In this work, we developed a highly sensitive fluorescent sensor by encapsulating boron‐doped graphene quantum dots (B‐GQDs) within amino‐functionalized lanthanum‐based metal‐organic ...

A Portable Radioisotope X-Ray Fluorescence Analyzer and Its Applications
RADIOISOTOPES, 1971 最近開発したポータブルRI線源螢光X線分析計とその鉱工業利用に関する研究について報告する。装置は測定プローブと電子回路部からなり, それぞれの重さは1.7kgおよび7kgである。X線分光法は, 比例計数管によるエネルギー分析を基本とし, 必要なばあいX線フィルターを用いる。現場で用いるときは, 測定元素の特性X線をスイッチの切換えで選択できる構造をもっている。この装置により合金, 鉱石その他の分析を行なった。鉱石試料の実験では, 元素量1%以上では通常, マトリックス補正なしの一次検量線を使用することができ, 平均濃度1%に対し, 相対誤差10%, 平均濃度15%以上に対し相対誤差3%以内という結果を得た。アルミ合金中のCu, 合金鋼中のV, Zr, Moにおいて, 10ppmオーダーの検出限界を,
