LIBS analyzer of LTB Lasertechnik Berlin at Hannover Messe 2015, 13-17 April
In research cooperation with the Federal Institute for Materials Research and Testing (BAM) and the Institut für angewandte Photonik (IAP), LTB Lasertechnik Berlin has successfully developed a analyzer for inline process control of complex substances, which combines laser-induced breakdown spectroscopy (LIBS) and x-ray fluorescence (XRF) technology in a single device.
The prototype has been used for inline process control in fertilizer production at BAM, which is based on the thermochemical treatment of phosphorous sewage sludge ashes at approx. 1000 °C in a rotary kiln. The system provides real-time analysis of major and trace elements like heavy metals, the ash may contain. This enables the immediate adjustment of significant process parameters to ensure the required quality of the fertilizer.
Inorganic residuals are considered as sustainable source of raw materials for the future because they often contain valuable components (”urban mining”). LIBS is a well-suited method that provides online analysis capabilities for industrial recovery of recyclable materials even under harsh environmental conditions.
The analyzer will be exhibited at the booth of BAM, 13 7 April, 2015:
Hall 2, booth A18
