Abstract

In this study, we have performed inner-shell electron impact action spectroscopy of mass and charge selected macromolecular ions. For this purpose, we have coupled a focusing electron gun with a linear quadrupole ion trap mass spectrometer. This experiment represents a proof of principle that an energy-tunable electron beam can be used in combination with radio frequency traps as an activation method in tandem mass spectrometry (MS²) and allows performing action spectroscopy. Electron impact MS² spectra of multiply protonated ubiquitin protein ion have been recorded at incident electron energies around the carbon 1s excitation. Both MS² and single ionization energy dependence spectra are compared with literature data obtained using the soft X-ray activation conditions.

VUV action spectroscopy of protonated leucine-enkephalin peptide in the 6-14 eV range

Journal Article Ranković, M. Lj. ; Canon, F. ; Nahon, L. ; ... - Journal of Chemical Physics

We have studied the VUV photodissociation of gas-phase protonated leucine-enkephalin peptide ion in the 5.7 to 14 eV photon energy range by coupling a linear quadrupole ion trap with a synchrotron radiation source. We report VUV activation tandem mass spectra at 6.7, 8.4 and 12.8 eV photon energies and photodissociation yields for a number of selected fragments. The obtained results provide insights into both near VUV radiation damage and electronic properties of a model peptide. We could distinguish several absorption bands and assign them to particular electronic transitions, according to previous theoretical studies. Furthermore, the photodissociation yields appear to bemore »« less

Laser-based studies with an ion-trap mass spectrometer: Ion tomography and analytical applications

Conference Alexander, M L ; Cisper, M E ; Hemberger, P H ; ...

The iron trap mass spectrometer (ITMS) is an ion storage device which consists of two hyperbolic endcaps and a hyperbolic ring electrode. This forms a trapping cavity having a volume of several cm{sup 3}. An rf potential applied to the ring electrode produces a time-varying potential which can be used to trap and/or manipulate ions under controlled conditions. This device has been used in ion trapping studies for a number of years. More recently, a commercial version has been produced and sold which allows for mass-selective ejection of trapped ions, with subsequent detection by an electron multiplier. In this mode,more »« less

Gas-Phase Synthesis of Singly and Multiply Charged Polyoxovanadate Anions Employing Electrospray Ionization and Collision Induced Dissociation

Journal Article Al Hasan, Naila M. ; Johnson, Grant E. ; Laskin, Julia - Journal of the American Society for Mass Spectrometry

Electrospray ionization mass spectrometry (ESI-MS) combined with in-source fragmentation and tandem mass spectrometry (MS/MS) experiments were used to generate a wide range of singly and multiply charged vanadium oxide cluster anions including V_xO_y ^n– and V_xO_yCl^n– ions (x = 1–14, y = 2–36, n = 1–3), protonated clusters, and ligand-bound polyoxovanadate anions. The cluster anions were produced by electrospraying a solution of tetradecavanadate, V₁₄O₃₆Cl(L)₅ (L = Et₄N⁺, tetraethylammonium), in acetonitrile. Under mild source conditions, ESI-MS generates a distribution of doubly and triply charged V_xO_yCl^n– and V_xO_yCl(L)^(n–1)– clusters predominantly containing 14 vanadium atoms as well as their protonated analogs.

A multiple-charged macromolecular accelerator for studying energetic cluster-surface interactions

Conference Reimann, C T

The interaction between an incident energetic polyatomic ion and a surface can give rise to a number of unique phenomena due to the high density of deposited energy and the occurrence of cooperative collision sequences during the impact. The physics of cluster-surface interactions is poorly understood at present, but research on this topic is stimulated by current issues in the areas of surface preparation and modification, and sputtering of biomolecules for mass analysis. In this presentation, the Uppsala multiply-charged macromolecular ion accelerator (MUMMA) is described. Mumma is based on an electrospray ionization source producing highly-charged protein ions which are acceleratedmore »« less
