NIR - Remote-Sensing and Artificial Neural Networks for Rapid Identification of Post Consumer Plastics
Th. Huth-Fehre,Roger Feldhoff,Th. Kantimm,L. Quick,F. Winter,Karl Cammann,W.H.A.M. van den Broek,D. Wienke,Willem J. Melssen,Lutgarde M. C. Buydens +9 more
TL;DR: An imaging spectrometer with a 256 element InGaAs diode array was combined with a high throughput optical arrangement for recording high quality NIR spectra (824 nm to 1700 nm) of plastics from a distance of 25 cm within 6.3 milliseconds as mentioned in this paper.
Journal ArticleDOI
Comparison of an adaptive resonance theory based neural network ( ART-2a) against other classifiers for rapid sorting of post consumer plastics by remote near-infrared spectroscopic sensing using an InGaAs diode array
D. Wienke,W. van den Broek,Willem J. Melssen,Lutgarde M. C. Buydens,Roger Feldhoff,Thomas Dr Kantimm,Thomas Huth-Fehre,L. Quick,F. Winter,Karl Cammann +9 more
TL;DR: It has been found by a cross validation scheme that MLF-BP networks show a slightly better discrimination power than ART-2a networks and both types of artificial neural networks perform significantly better than the SIMCA method.
Journal ArticleDOI
Investigations for the determination of lead by in situ hydride trapping within a graphite electrothermal atomizer for routine analysis
TL;DR: A new commercial system consisting of a flow injection analysis system for hydride generation coupled with a transversely heated graphite atomizer-atomic absorption spectrometer for the determination of lead is investigated in detail, showing the efficiency of the method in combination with decomposition with aqua regia solutions.
Journal ArticleDOI
Simultaneous multielement determination in complex matrices using frequency-modulated electrothermal atomic absorption spectrometry
H. Edel,L. Quick,Karl Cammann +2 more
TL;DR: In this paper, the simultaneous multielement atomic absorption spectrometric (FREMSAAS) determination of cadmium and lead, iron and chromium, and cooper and manganese in several complex matrices is presented.
Journal ArticleDOI
Fast Identification of Packaging Waste by near Infrared Spectroscopy with an InGaAs Array Spectrograph Combined with Neural Networks
Roger Feldhoff,Thomas Huth-Fehre,Thomas Dr Kantimm,L. Quick,Karl Cammann,Willie van den Broek,D. Wienke,Harald Fuchs +7 more
TL;DR: An optical set-up consisting of a high-throughput NIR spectrometer with an InGaAs array (800 nm to 1700 nm) and a specially designed collection optics was used to record spectra from post consumer packages (PE, PET, PP, PS and a cardboard-plastic compound) located on an industrial conveyor belt with an integration time of 6.3 milliseconds per sample.
