Webincluded that modify previously used methods to obtain lower detection limits and/or to improve accuracy and precision. Fluorine gas is too reactive to exist in biological or environmental samples. Indeed, fluorine is too reactive to be analyzed directly by conventional methods, but rather is quantitatively converted to WebExcitation range and maximum. An excited fluorophore molecule emits lower-energy light than the light it absorbs. Therefore, there is always a shift along the spectrum between the color of the light absorbed by the fluorophore during excitation, and the color emitted. A fluorescent dye absorbs light over a range of wavelengths—and every dye ...
