How does a fluorometer work
WebA fluorometer (and fluorimeter) measures the fluorescence or light emitted by different fluorescing objects. Fluorescence occurs when light of specific wavelength hits and … WebA fluorometer (sometimes fluorimeter) is a spectrometer designed to measure this phenomenon. The first part of the fluorometer is very similar to the spectrophotometer, and consists of a light source and a filter or monochromator to select out a defined group of excitation wavelengths, which are then directed into a sample. ...

Wavelength selectors come in two types; fixed wavelength or scanning.
WebFluorescence is a type of luminescence caused by photons exciting a molecule, raising it to an electronic excited state. Fluorescence spectroscopy uses a beam of light that excites the electrons in molecules of certain compounds, and causes them to emit light. That light is directed towards a filter and onto a detector for measurement and ... A fluorometer, fluorimeter or fluormeter is a device used to measure parameters of visible spectrum fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. These parameters are used to identify the presence and the amount of specific molecules in a … See more Typically fluorometers utilize a double beam. These two beams work in tandem to decrease the noise created from radiant power fluctuations. The upper beam is passed through a filter or monochromator and passes through … See more There are two basic types of fluorometers: the filter fluorometers and spectrofluorometer. The difference between them is the way they select the wavelengths of incident light; filter fluorometers use filters while spectrofluorometers … See more Dairy industry Fluorimetry is widely used by the dairy industry to verify whether pasteurization has been … See more • Fluorescence spectroscopy, for a fuller discussion of instrumentation • Chlorophyll fluorescence, to investigate plant ecophysiology.
