Abstract
Description
・洗浄サイクル:洗浄ガスポンプ10が作動し、弁8が開いており、一方弁7は閉じている。測定ガス送出ポンプ9はオフになっている。洗浄ガスが中空ファイバ1を貫流し、残留測定ガスを測定ガス雰囲気15へ流し戻す。十分な洗浄時間の後に光吸収測定が行われ、まず最初に、洗浄ガスを充填された中空ファイバ内のガス容積に関してゼロ点測定が行われる。
濃いアルカリ溶液中にアルミニウムまたはシリコンの溶解
Al+NaOH+3H2O→Na[Al(OH)4]+(3/2)H2
この反応は苛性ソーダ溶液へのAlの添加によって開始する。十分なガス量が生成されているときは、Alの供給を停止する。この装置は、NaOHおよびたとえばチップの形態のAlのためのそれぞれ1つの備蓄容器と、アルミニウムチップの調量装置と、ガス送出ポンプとで構成される。この構造は化学品の備蓄や洗浄サイクルの回数に依存して、複数年にわたって洗浄ガスを供給することができる。
赤熱した銅に空気を通し、それによって酸素を完全に取り除くことができる。残るのは窒素と1%のアルゴンとの混合物であるが、アルゴンに支障はない。この場合、CuおよびCuの加熱部のほかにガス送出ポンプが必要となる。プロセスは、測定セルが洗浄されるべきときにだけ進行する。基本的に、メンテナンスが必要なのは銅の交換だけである。洗浄サイクルの回数と所要のガス量に応じて、この装置も複数年にわたってメンテナンスなしで利用することができる。
硫酸で酸性化された過酸化水素溶液に過マンガン酸カリウム溶液を滴下することによって、厳密に算定可能な量で酸素を調製することができる。この場合、調量されながら反応容器内へ導入される化学薬品の2つの備蓄容器と、ガス送出ポンプとが必要である。このプロセスは次のように進行する。
洗浄を開始したいときに、所望の酸素量に相当する容積の過酸化水素を反応容器に用意して、過マンガン酸カリウムを滴下する。
