UV/Vis SpectrometerModel: Agilent 8453 Contact: Carina Dargel
The Agilent 8453 UV-visible spectroscopy system is equipped with a combination of deuterium-discharge lamp and a tungsten lamp to cover the UV/Vis wavelength range from 190-1100 nm. As detector a photodiode array is used which allows fast measurement of the whole spectrum. Besides conventional absorption measurements, the setup is used to monitor absorption changes time or temperature dependently, e.g. for different kinds of kinetics or phase transitions. Thereby, the tempered 8-position sample holder allows simultaneous sample measurements with precise temperature control using PT-104A resistance thermometer.
