Description
図5は、変形例における処理部50による処理動作の手順を説明するためのフローチャート図である。この変形例は、分光分析装置1により、試料に含有される水と水以外の含有物質の存在比を測定する例である。図4の手順にステップS407が追加され、ステップS408がステップS409で置換された点が、図4の手順と異なるが、他のステップは図4と同じである。以下、図4と異なるステップについて説明し、重複するステップについての説明は省略する。
図6は、別の変形例における処理部50による処理動作の手順を説明するためのフローチャート図である。この変形例は、例えば産業プロセスで搬送される試料Sのインライン測定において、試料Sの状態が想定外の変動を示す場合に、そのような変動を検出するための分光分析装置1の動作手順に関する。水のピークの吸光度が不変であるにもかかわらず試料Sの屈折率が変動するような場合、温度変化又は水以外の分子の混入が生じている可能性がある。よって、分光分析装置1の処理部50は、水のピークの吸光度と試料Sの屈折率とを比較することにより、想定外の変動の有無を判断すると警告を出力する。図6は、図4の手順におけるステップS408がステップS407´により置換され、ステップS409´及びS412が追加された点が、図4の手順と異なるが、他のステップは図4と同じである。以下、図4と異なるステップについて説明し、重複するステップについての説明は省略する。
