Preferred Label : fluorimeter;
IUPAC definition : An instrument used to measure the intensity and the wavelength distribution of the
light emitted as fluorescence from a molecule excited at a specific wavelength or
wavelengths within the absorption band of a particular compound. Characteristic fluorescence
bands may be used to identify specific pollutants such as the polynuclear aromatic
hydrocarbons. Excitation spectra of impurities can be observed by scanning the wavelength
of the excitation light which is incident on the sample over a range of wavelengths
and observing the relative intensity of the fluorescence emitted at a given wavelength.
These spectra are also characteristic of the impurity.;
