To understand life phenomenon, it is important to reveal the functions and structures of biomolecules. However, it is difficult to study properties of proteins and nucleic acids which constitute a living body because they interact with other biomolecules and water molecules in vivo. In this research, sodium added guanine multimer ions (GnNa+, n = 1~4) or potassium added guanine multimer ions (GnK+, n = 1~8) were generated in a vacuum using electrospray ionization. We examined DC voltage of octapole ion guide (OPIG-DC) dependence and reaction temperature dependence of collision-induced dissociation (CID). Information relate to steric structure was obtained from CID research. The results indicate that CID of GnNa+ or GnK+ is promoted at high temperature or high OPIG-DC voltage. It is inferred that as reaction temperature or OPIG-DC voltage increases, the collision energy, the collision frequency, and the internal energy of ions increase.
