A injected sample (acid or base), combined with a carrier (deionized water), was mixed with a reagent (base or acid) stream. A change in the solution temperature was detected by passing the solution, immediately after mixing, through a stainless steel capillary tube around which a thermo-sensitive resistance was coiled. The temperature of carrier was used as a reference Hydrochloric acid solutions of 0.003 to 0.2M could be determined at a rate of 120 smples/h. Using this system, determination in weak-acid and weak-base system could also be performed. Thermo-sensitive resistances used in this work were completely free from corrosion, and effects of the ambient temperature and the sample diffusion in the detector were minimized., 中和熱を利用した酸-塩基のフローインジェクション分析法を提唱する。注入された試料(酸または塩基)はキャリア(脱イオン水)によって流され、試薬(塩基または酸)と合流混合される。ミキシング直後の温度変化をステンレスチューブに巻いた感温抵抗体にて検出する。キャリアの温度を参照として用いた。0.003から0.2Mの塩酸溶液を120試料/時の速度で定量することが出来た。この方法を用いると弱酸-弱塩基の系でも分析が可能であった。感温抵抗体は腐食から完全に免れており、かつ環境温度の影響や検出部における試料の拡散が低減された。, http://aitech.ac.jp/~jafia/japanese/index.html}, pages = {66--76}, title = {Flow Injection Analysis of Acid and Base using Thermo-Sensitive Resistance Coils}, volume = {12}, year = {1995}, yomi = {トダ, ケイ and イワタ, センジュ and サネマサ, イサオ and デグチ, トシオ and トダ, ケイ and イワタ, センジュ and サネマサ, イサオ and デグチ, トシオ} }
