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.

Devices and methods for inspecting containers for the presence of foreign matter include, in at least one embodiment, at least one sampling head, at least one pressure sensor, and a filter. The at least one sampling head is configured to introduce an amount of a first fluid into a container and to remove an amount of a second fluid from the container for inspection for the presence of foreign matter. The at least one pressure sensor is configured to measure a pressure of the second fluid upon removal of the second fluid from the container. The filter is arranged in the at least one sampling head and is configured to filter the second fluid.
