Compact system capable of performing many new functions such as sensitivity (S/N 800:RMS) and ultra high-speed (60,000nm/min) at the highest level of its class. The application of fluorophotometry has been expanded to various fields such as industrial materials, in areas such as organic electroluminescence and liquid crystals; environment-related areas, such as water quality analysis; pharmaceutical manufacturing, such as the synthesis and development of a fluorescence reagent; and to biotechnology-related areas, such as intracellular calcium concentration measurement.
