Moreover, we have overcome the challenge in the convolution of spectral signals with complex backgrounds that arise from e.g., paper/fabric-soaked samples.

We show the utility of this device in decreasing the flow of synthetic cannabinoids (SCs) into prisons, the identification of SCs in vape liquid and direct from unopened vape pens, and the identification of benzodiazepine tablets.
