Description
Among instrumental techniques, fluorescence spectroscopy is
recognized as one of the more sensitive. In fluorescence, the
intensity of the emission of the sample is measured. The reason
for the high sensitivity of fluorescence techniques is that the
emission signal is measured above a low background level. This
is inherently more sensitive than comparing two relatively large
signals as in absorption spectroscopy. The sensitivity of
fluorescence techniques is as much as 1000 times more sensitive
than absorption spectroscopy.
