The pressure requirements for chemical ionization g.c./F.t.m.s. which restrict mass resolution and accuracy are overcome through use of a pulsed valve that provides momentary reagent gas pressures. For alternate electron impact (EI)/chemical ionization (c.i.) g.c./F.t.m.s., similar resolution for bo

The stored waveform inverse Fourier transform (SWIFT) technique is used for broadband excitation of ions in an ion-trap mass spectrometer to perform mass-selective accumulation, isolation, and fragmentation of peptide ions formed by matrix-assisted laser desorptionlionization. Unit mass resolution i
In this work we demonstrate the use of peptide as a stable internal mass standard to obtain accurate mass measurements of infrared multiphoton dissociation (IRMPD) generated phosphorothioate oligonucleotide fragment ions. Because oligonucleotides are more readily dissociated in the gas phase by IRMP
