In the image, the resolved chemical components appear as glowing bands on a high-performance thin-layer chromatography plate and can be identified by surface sampling mass spectrometry. Gary Van Berkel and his group at the Oak Ridge National Laboratory working under the BES program of "Sampling, Ionization and Energy Transfer Phenomena in Mass Spectrometry" advances the role of mass spectrometry for surface sampling purposes.
