We have been trying to establish technologies to identify chemical species of atoms and molecules using scanning probe technology (SPM). Among several possible techniques, we have combined SPM with mass spectrometer (SPM/FIM/AP), magnetic force control (MFC-AFM), low temperature technology, and ultra-high sensitivity near-field vibrational spectroscopy (SNOM/Raman), and so on. In this talk, I will show a couple of them stressing on their instrumentation and demonstrative results. These works have been carried out in collaboration with T. Shimizu, A. Bruckbauer, M. Futamata, S.P. Jarvis, M. Kageshima, N. Choi, and T. Uchihashi at JRCAT under the support by NEDO.
