Abstract
A method of detecting sample substances separated by an analytical separation technique, for example liquid chromatography or capillary electrophoresis, using electromagnetic radiation, and a corresponding fluorescence spectrometer are disclosed. The spectrometer comprises: PA1 a flashlamp for emitting pulses of light, PA1 an adjustable diffraction element for adjusting selectable measuring wavelengths, PA1 a sample cuvette through which sample substances to be detected flow, detection means for receiving fluorescence light emitted from said sample substances flowing through said sample cuvette, and PA1 control means for adjusting different measuring wavelengths by corresponding control of said adjustable diffraction element, and for synchronizing the emission of light pulses from said flashlamp with said adjusting of different measuring wavelengths.
