…In general, infrared light is used to identify substances, while visible and ultraviolet light are often used to quantify them. Visible light absorption spectroscopy is also called colorimetry or colorimetric analysis, which comes from the fact that historically, absorption intensities were compared with the naked eye. When quantifying a substance, a wavelength specific to the substance being measured is set, and the absorbance A at this wavelength is calculated. … *Some explanations of terms that mention "colorimetric analysis" are listed below.

…一般的には赤外部は物質の同定に,可視・紫外部は物質の定量に利用されることが多い。可視部の吸光光度法は比色法または比色分析colorimetric analysisとも呼ばれるが,これは歴史的に肉眼で吸収強度を比較していたことに由来する。 物質の定量に際しては,測定される物質に固有の波長を設定し,この波長における吸光度Aを求める。… ※「colorimetric analysis」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
