Spotting isomer mixtures in forensic illicit drug casework with GC–VUV using automated coelution detection and spectral deconvolution

•GC-VUV deconvolution capabilities allow for isomeric mixture detection.•Severe coelution of isomers with very identical spectra is correctly identified.•Coelutions are detected independent of the presence of compounds in the library.•A
