A novel chemiluminescence analysis to taked advantage of a specific chemiluminescence reaction space around the liquid-liquid interface in a micro-channel under laminar flow conditions has been reported. We call the analytical system "micro-channel chemiluminescence analysis (MCCLA)". First, the concept of micro-channel chemiluminescence analysis and its features were described and considered through direct observations of fluorescence and chemiluminescence using a fluorescence microscope-CCD camera and a microscope CCD camera. Next, several concrete examples of micro-channel chemiluminescence analysis were introduced, and the experimental data were basically discussed. A fluorescence compound was examined by micro-channel chemiluminescence analysis using an oxalate chemiluminescence reaction. Anti-oxygen, beverages, and saliva were also investigated by chemiluminescence analysis using a singlet oxygen chemiluminescence reaction. Furthermore, we have developed a capillary chromatography using an open capillary tube and a water-hydrophilic/hydrophobic organic solvent mixture as a carrier solution ; the system works under laminar flow conditions. The capillary chromatography is called a tube radial distribution chromatography (TRDC) system.
