Analytical Instrument
Edinburgh Instruments LP980 Transient Absorption Spectrometer
Model LP980 is the successor model of the classic LP920 from Edinburgh Instruments.  It uses ND:YAG laser or OPO as the strong pulse excitation source and high energy xenon lamp as a detection/background source to perform transient absorption measurement DownloadOnline messages

Features:

·         Dual sample compartment - pump detection technology to detect chemical and biological transient species, laser-induced fluorescence and phosphorescence detection life (as low as ns)

·         Detection limit of laser flash photolysis at ΔOD 0.002 (fast detection option), at Δ0D 0.0005 (slow detection mode)

·         300mm focal length monochromator – built-in automatic filter wheel to eliminate the second diffraction peak

·         New 150W xenon light source, 100A pulse current - High light intensity, high SNR, to provide a more stable background signal for long life time testing

·         Internal laser beam adjustment - prevents external beam interference

·         Integrated software to have full control of LP980 transient absorption spectrometer

·         Optional Raman attachment for coupling of fluorescence steady-state and Raman spectroscopy measurement


Applications:

Transient absorption / Laser Flash Photolysis is a technique for studying transient chemical and biological species generated by the short intense light pulse from a nanosecond pulsed laser source (pump pulse). This intense light pulse creates short

lived photo-excited intermediates such as excited states, radicals and ions. All these intermediates are generated in concentrations large enough for chemical and physical interaction to occur and for direct observation of the associated temporally changing absorption characteristics samples.


·         Laser-Induced Fluorescence Spectroscopy (LIF)

·         Laser-Induced Breakdown Spectroscopy (LIBS)

·         Photobleaching

·         Triplet-Triplet Annihilation

·         Oxygen quenching of transient absorption decays
