described. Differential photometric detection using UV-visible absorbing eluents enabled us to examine the retention and detection mechanism of sample and eluent ions in ion exchange chromatography. Photometric detection in ion chromatography determined transparent ionic compounds using indirect photometric detection mode of this theory. This method was useful for many samples such as environmental water and foods. Polarized photometric detection method has been developed by introducing two polarizers on either side of the UV-visible absorbance detector flow cell. The monitor determined optically active compounds as the change in absorbance. This method was applied for determining food additives such as sugars and organic compounds. A HPLC system with a chemiluminescence detector has been developed for the determination of trace levels of mutagenic nitroarenes such as 1, 3-, 1, 6-, 1, 8-dinitropyrenes and 1-nitropyrene. Utilizing this system, their exhaust from vehicles and behavior in air were examined in detail. This system was also used for determining methamphetamines in abuser urine and hair.

概要:
金沢大学医薬保健研究域薬学系<br />これまで, 液体クロマトグラフィーにおける吸光度検出器は専ら光吸収を有する化合物を検出する装置であり, その原理と検出器は既に完成されたものとの印象が強かった.本総説は, 上述の概念を大きく変革しつつ

ある吸光度検出法の新展開として, 光吸収のない対象物質を検出できる間接吸光度検出法と, 更にその考え方を光学活性物質の検出に向けた偏光吸光度検出法に焦点を合わせ, 著者らの研究成果も含めて紹介する. New photometric detection methods developed for use in liquid chromatography have been reviewed. Differential photometric detection using UV-visible absorbing modifiers enabled us to examine the retention and detection mechanism of not only analytes but also mobile phases. Indirect photometric detection ion chromatography based on this theory separately and sensitively determines ionic compounds using a conventional high-performance liquid chromatographic system with a UV-visible absorbance detector. This method is useful for many kinds of samples such as environmental water, foods and biological materials. Polarized photometric detection mathods with two polarizers on either side of a UV-visible absorbance detector flow cell have been developed. The monitor determines optically active compounds as the change in absorbance. This method was effectively applied for determining sugars and organic acids
