Studies on the feasibility of laser-induced breakdown spectroscopy in explosion proof atmospheres

摘要

One of the latest major innovations of the Institute for Mining and Metallurgical Machinery (IMR) is the adaption of a laser-induced breakdown spectrometer (LIBS) into the harsh conditions of surface mines. Usually working in the clean environment of laboratories, a compact analyzer consisting of a laser system and a spectrometer was developed to work in harsh environments which are affected by dust, mist, vibration and shock. Now, IMR is working on adjusting this laser system to underground conditions which are aggravated by the possibilities of methane explosions such as in hard coal mines. This project focusses on the conception of the enclosure and it's sampling for LIBS analysis. It is funded by the German Research Foundation (DFG).
