Paper Abstract

Environmental science is concerned about the content of dissolved heavy metals in coastal tidal waters. Fluorescence spectroscopy methods do offer a chance for the detection of dissolved chromium. Due to strong quenching processes in liquids, optical emission spectroscopy often lacks sensitivity. In this study we intended to use subsequent Nd:YAG Q-switched laser pulses to create a plasma directly in front of an optical fiber tip. The plasma emits light at characteristic chromium wavelengths. The emitted fluorescence was recorded using an optical multi-channel analyzer.
