Description
透過率(T)が%T=(Isample/Iblank)*100で計算され、吸収率がAbs =−log(Isample/Iblank)で計算される。この結果は、例えば410に示すように、励起波長の関数としてプロットすることができる。無論、特定の用途および実装に応じて他の各種のデータ取得および分析技術を用いてもよい。
Fideal=Fobserved*exp((ODex+ODem)/2)
ここに、Fidealは内部フィルタ効果が存在しない場合に期待される理想的な蛍光信号スペクトルを表し、Fobservedは観察された蛍光を表し、ODexおよびODemはEEMの各励起および発光波長座標で測定された吸収値を表す。また、本システムまたは方法は、ブロック606で表すように、モノクロメータから光の一部を受光すべく配置された基準検出器により検出される光度に基づいて吸収測定値を調整するステップを含んでいてよい。
