Simulation Study to Improve Ion Transmission Efficiency in Mass Spectrometry with a Dual Ion Funnel Ion Source

Autor: Hyun Sik Kim, Seung Yong Kim, Taeman Kim, Sun Jong Baek

Publikováno v: Mass Spectrometry Letters. 4:91-94

We performed computer simulations to improve transmission efficiencies of a dual ion funnel system implemented on an FT-ICR MS. We found that the low m/z range from 50 to 150 could be significantly improved by operating the two ion fun- nels at diffe

Simulation-based optimization of the electrodynamic ion funnel for high sensitivity electrospray ionization mass spectrometry

Autor: Jean H. Futrell, Richard D. Smith, Thomas H. Bailey, Harold R. Udseth, Aleksey V. Tolmachev, Taeman Kim

Publikováno v: International Journal of Mass Spectrometry. 203:31-47

High sensitivity is one of the most important requirements for applications of electrospray ionization mass spectrometry (ESI MS). Recent work with the electrodynamic ion funnel has demonstrated that it can provide significantly improved ion transmis

Electron transfer dissociation in the hexapole collision cell of a hybrid quadrupole-hexapole Fourier transform ion cyclotron resonance mass spectrometer

Autor: Michael L. Easterling, Andreas Brekenfeld, Dmitry R. Gumerov, Carsten Stoermer, Frank H. Laukien, Taeman Kim, Desmond Allen Kaplan, Ralf Hartmer, Melvin A. Park, J. Paul Speir

Publikováno v: Rapid communications in mass spectrometry : RCM. 22(3)

Electron transfer dissociation (ETD) of proteins is demonstrated in a hybrid quadrupole-hexapole Fourier transform ion cyclotron resonance mass spectrometer (Qh-FTICRMS). Analyte ions are selected in the mass analyzing quadrupole, accumulated in the

A multicapillary inlet jet disruption electrodynamic ion funnel interface for improved sensitivity using atmospheric pressure ion sources

Autor: Harold R. Udseth, Keqi Tang, Richard D. Smith, Taeman Kim

Publikováno v: Analytical chemistry. 73(17)

A new multicapillary inlet and ion funnel interface for electrospray ionization-mass spectrometry has been developed and demonstrated to achieve higher ion transmission efficiency compared to a single-capillary inlet and ion funnel interface. Even th

Improved ion transmission from atmospheric pressure to high vacuum using a multicapillary inlet and electrodynamic ion funnel interface

Autor: Harold R. Udseth, Richard D. Smith, Taeman Kim

Publikováno v: Analytical chemistry. 72(20)

A heated multicapillary inlet and ion funnel interface was developed to couple an electrospray ionization (ESI) source to a high-vacuum stage for obtaining improved sensitivity in mass spectrometric applications. The inlet was constructed from an arr
