Chirascan may be equipped with an optiona dedicated fluorescence detector for measurement of total fluorescence or scattered light using the side port of the sample handling unit. The standard TF.3 detector comprises a housing fitted with a photomultiplier tube capable of measurement in the range 300-650nm (alternative PMTs are available for extended wavelength range operation) and detector mounting for the side port. It is suitable for measuring signal changes as a function of time, concentration or temperature and can also be used to record fluorescence excitation spectra.
