Agilent LC/Q-TOF Mass spec

Liquid chromatography (LC) separates the sample components and then introduces them to the mass spectrometer (MS). The MS creates and detects charged ions. Once detected, spectra of relative abundance against the ratio of mass/charge (m/z) are generated. These spectra are used to determine molecular masses of molecules under investigation, provide more data for structural elucidation, detect reaction (by) products.

Agilent Cary Eclipse Fluorescence Spectrometer with micro well plate reader

Fluorescence spectroscopy can be coined as one of the most prominent applied domain of spectrophotometry. It is an inherent property of many aromatic/organic compounds. Fluorescence is not an isolated event. It typically occurs alongside phosphorescence, which together makeup luminescence. Luminescence is emission of light from a substance resulting from changes in excited states, but with fluorescence and phosphorescence, differ based on the nature of the excited state. When an electron is excited, and occupies an excited-state orbital, it possesses an opposite to the electron in the ground state. Thus the return to the ground state from excited state is spin allowed and occurs via emission of a photon.
