Fluorescence detection is a detection method that uses fluorescence emitted when a compound returns to the ground state after transitioning to the excited state. Fluorescence detection has been widely used as a practical detection method in HPLC analysis. The slim housing allows the optical detector to slip into tight setups. Improvements in throughput and resolution optimisation, allow faster experiments with improved results. HEXITEC. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.It is a form of luminescence.In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation.A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the Vanquish Fluorescence Detectors are easy to use and provide you with an unmatched detection experience. Therefore, the key to fluorescence detection is the stable control of the excitation light and the accurate acquisition of weak photoelectric signals.
