| Definition | The amount (mass or moles) of all forms of the the pigment chlorophyll-a except divinyl chlorophyll-a measured in a unit volume of any fresh or salt water body, contained in particles collected using an unspecified filter. The sample is irradiated by light of a specific excitation wavelength causing the substance of interest to fluoresce. The intensity of the fluorescence emitted is detected as a function of wavelength or time. Synonyms include fluorescence spectrometry, spectrofluorometry, and fluorescence emission spectroscopy. | ||
