WebThe mobilities of a set of common α-amino acids, four tetraalkylammonium ions, 2,4-dimethyl pyridine (2,4-lutidine), 2,6-di-tert-butyl pyridine (DTBP), and valinol were determined using electrospray ionization-ion mobility spectrometry-quadrupole mass spectrometry (ESI-IMS–QMS) while introducing 2-butanol into the buffer gas. WebIon mobilities decreased to different extents due to clustering with 2-butanol, resolving compounds with similar mobilities. Mobilities of ions were determined using IMS–MS while introducing 2-butanol into the buffer gas. …
