有機液体マトリックス中の軽元素は、後方散乱X線放射を使用して定量された[Molt K等、X−Ray Spectrometry 28(1):59〜63、1999]。Molt等は、主成分及びDXRSスペクトルの共変法(co−variant method)を使用して有機液体のC、H、及びOを定量した。
CE=%C+%Mn/6+(%Cr+%Mo+%V)/5+(%Cu+%Ni)/15
以下の実施例は、本発明のプロセスを説明することを単に目的としており、本発明を限定するものではない。
鋼サンプルの炭素含有量を定量するために本発明により開発されたプロセスを使う場合、従うべき手順は以下に記載の通りである。
ここに示される説明のための実施例では、Shimadzu EDX 700の蛍光X線装置を使用したが、これに限定されるものではない。標準サンプルを、前処理なしにロジウムX線源の多色放射にさらした。サンプルのスペクトルを得るために同一手順を行うべきである。測定は、各サンプルに対して3回実行するべきである。分析されるスペクトル領域は、5.412keV〜22.0keVとするべきである。
適切なソフトウェアを使用する。実施例1で説明した手順に従う。
