摘要
A 255 nm deep-UV-light-emitting diode (deep-UV-LED) is investigated as a novel light source for photometric detection in view of fundamental properties of UV-LEDs, in particular emission spectra and energy conversion. Its performance in on-capillary photometric detection in capillary electrophoresis (CE) is determined and the potential of deep-UV-LEDs in optical detection is discussed.
