Application of Gas Chromatography to the Analysis of Developing Agents in a Photographic Developer

Abstract

Developing agents in a photographic developer have been determined by means of the titration or the absorption spectra measurement for the extract from a developer. Performance of these methods takes much time and requires a great deal of skill. It was thought desirable to investigate the use of gas chromatography as a sensitive technique for the analysis of developing agents. This paper demonstrates the rapid analysis by gas chromatography of developing agents in a photographic developer. The chromatogram represented species and concentrations of developing agents was obtained by directly injecting a small aliquot of a photographic developer. This method is far simpler than usual methods and may be recommended for control analyses of developing agents as well as for studies of chemical reactions involved in a photographic development.
