Why has GC-MS (gas chromatography- electron impact ioniation- mass spectrometry) had such enduring value for the field of metabolomics? How do we identify metabolites based on mass spectrometry data?

I hope you'll enjoy this video explaining the basics of GC-MS and the spectral library methods we use for explaining these spectra!
