Spectrofluorometers are designed to detect and quantify fluorophores. These are fluorescent molecules that, when exposed to light, absorb photons at a characteristic wavelength. Subsequently, they then emit photons at a different and slightly longer characteristic wavelength. Spectrofluorometers contain excitation and emission filters for using different fluorophores. Monitoring the activities of molecules labeled with fluorophores is crucial to many kinds of experiments in cell biology, molecular biology and genetics, pharmaceuticals, and forensics, among many others. Emitted light may be detected by photomultiplier tubes or photodiodes within the spectrofluorometer, depending on the model. In addition, users of spectrofluorometers now have a wide range of high-tech fluorophores from which to choose to complement the features of a Spectrofluorometer, also referred to as fluorimeter. Modern fluorometers and fluorimeters are capable of detection as low as 1 part per trillion.

It uses the pump-probe technique for measuring transient kinetics and sepctra. In kinetic mode (K) a single point detector is used to measure the transient kinetics at a single wavelength (spectra can be built up by automated scanning over a wavelength range and slicing the data). In spectral mode (S) a gated intensified CCD is used to capture the whole spectrum in the presence and absence of the pump laser pulse, meaning the whole spectrum can be generated after one laser pulse. The LP980 spectrometer has a dual sample chamber that enables users to reliably and accurately measure transient chemical and biological species up to 2.55 µm using the pump-probe technique AND laser-induced fluorescence lifetimes down to nanosecond time ranges.
Transverse sample excitation geometry comes as standard. Thin-film, diffuse reflection, fluorescence and phosphorescence lifetime measurement accessories are available as options.... Read More |
