1. A method, comprising:
causing, by a device that includes a processor, one or more spectrometers to perform one or more spectroscopic measurements of an unknown sample;
determining, by the device and based on causing the one or more spectrometers to perform the one or more spectroscopic measurements of the unknown sample, that the unknown sample is not included in a no-match class relating to at least one material that is not of interest or a baseline spectroscopic measurement;
performing, by the device, one or more spectroscopic determinations based on determining that the unknown sample is not included in the no-match class;
determining, by the device and based on performing the one or more spectroscopic determinations, a classification failure or a classification success for the unknown sample; and
performing, by the device, one or more actions based on determining the classification failure or the classification success for the unknown sample.
