Fluorescence Detector

Some substances can emit light when they are subject to UV light (excitation). They then emit light at a longer wavelength (emission). For more information, also see Fluorescence. A fluorescence detector detects the light emitted from fluorescent substances. The detector is usually position at an angle of 90° to the light source.

The advantage over UV Detectors is that the sensitivity may be 1000 times greater.

 Note:

You can also use certain fluorescence detectors to measure the Phosphorescence and Chemiluminescence.
