Recent advances in Gas-Chromatography–Mass Spectrometry (GC–MS) analytical techniques and more targeted technologies, such as Ion Mobility Spectroscopy (IMS), Surface Acoustic Waves–Mass spectrometry (SAW–MS), and Gas Chromatography–Surface Acoustic Waves–Mass spectrometry (GC–SAW), shows a clear trend at reducing the size, the analysis time as well as the costs of installation and deployment.
