生体分子イオンのプロトン移動反応のOPIG-DC依存性に関する研究

(横市大院生命ナノ)
o野々瀬真司豊見山蒼樹石井空雅笹野光紀吉野壮悟

OPIG-DC-resolved proton transfer reactions of biomolecular ions to 1,5-pentanediamine (Peda) were examined in the gas phase. Absolute reaction rate constants for proton transfer were determined from intensities of precursor and product ions in the mass spectra. With changes of direct current (DC) voltage to put octapole ion guide (OPIG) of the collision cell, remarkable change was observed for distribution of the product ions and the reaction rate constants. The results indicate that conformation changes on ions at OPIG-DC voltage range, which relate with complex formation. An issue that is attracting considerable attention is their conformations might resemble structural evolution that originated from internal energy in the gas phase.
