FLUORESCENCE SPECTROSCOPY

What is it?

Fluorescence spectroscopy can be used to identify and analyze fluorescent compound at very low concentration (in the parts per billion range) while providing information about structure, formulation, and stability.  Both solids and liquid samples can be analyzed using fluorimetry.  Fluorescence spectra are produced when ions or molecules absorb electromagnetic radiation at short wavelengths (higher energy) and are capable of radiating at longer wavelengths (lower energy).  Besides uniquely identifying fluorescent compounds, these spectra provide information on the structure of fluorescent substances.
