A fluorescence spectrometer is a device to detect and analyze organic compounds. Used in biology, chemistry, and environmental science laboratories, the fluorescence spectrometer measures the fluorescence of a molecule to gather information about its components and chemical environment. The two main types of fluorescence spectrometers are filter fluorometers, which use filters to isolate the different types of light, and spectrofluorometers, which isolate the types of light with diffraction grating monochromators. When choosing a fluorescence spectrometer, consider the wavelengths it can analyze, the time analysis takes, and the amount of sample needed for analysis.
