Abstract: Apparatus and methods for identifying substances in a material include at least one light source configured to irradiate a sample of the material with light of at least one wavelength. A detector is configured to detect light re-emitted or transmitted by the sample. An analysis device analyzes the detected light by UV/VIS spectroscopy, fluorescence spectroscopy, Raman spectroscopy, or absorption spectroscopy, and generates a first identification result for at least one substance of the sample. Further, the analysis device generates a second identification result in response to the first identification result being an ambiguous identification result. The second identification result may be generated by fluorescence light decay time analysis (FLZA). At least one substance is at least partially identified based on the first identification result or based on the first and second identification results.
