method for the detection of probensubstanzen and fluoreszenzspektrometer by this method

摘要

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: a flashlamp (1) for emitting pulses of light, an adjustable diffraction element (8; 20) for adjusting selectable measuring wavelengths, a sample cuvette (13) through which sample substances to be detected flow, detection means (26) for receiving fluorescence light emitted from said sample substances flowing through said sample cuvette, and control means (3,27) 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.
