A three section linear or two dimensional (2D) quadrupole ion trap as a high performance mass spectrometer is described. Mass analysis is performed by ejecting ions radically out a slot formed in one of the rods using the mass selective instability mode of operation. The slot geometry is optimized to yield high ejection efficiencies. and an introduction to Resolution Quadrupole and Ion Trap ...

Londry and James W. Hager MDS SCIEX, Concord, Ontario, Canada The electric fields responsible for mass selective axial ejection (MSAE) of ions trapped in a US4540884A Method of mass analyzing a sample by use of a ... In a quadrupole ion store or ion trap type mass spectometer, significantly improved mass selection is achieved by simultaneously trapping ions within the mass range of interest and then scanning the applied RF and DC voltages or the frequency ω to sequentially render unstable trapped ions of consecutive specific masses. These are passed out through apertures in an end cap to a high gain ... Quadrupole ion trap Wikipedia A quadrupole ion trap is a type of ion trap that uses dynamic electric fields to trap charged particles. They are also called radio frequency (RF) traps or Paul traps in honor of Wolfgang Paul, who invented the device and shared the Nobel Prize in Physics in 1989 for this work. It is used as a component of a mass spectrometer or a trapped ion quantum computer Ion Trap Mass Spectrometry currentseparations.com Ion Trap frequency 104 104 104 Quadrupole mass filter filters for m z 103 104 103 104 105 T1 Characteristics of Differ ent Mass Analyzers.

Quadrupole ion trap chemeurope.com A quadrupole ion trap exists in both linear and 3D (Paul Trap, QIT) varieties and refers to an ion trap that uses DC and radio frequency (RF) oscillating AC electric fields to trap ions. It is a component of a mass spectrometer that would use such a trap to analyze ions. The invention of the 3D quadrupole ion trap itself is attributed to Wolfgang Paul who shared the Nobel Prize in Physics in ... Ion trap Wikipedia An ion trap mass spectrometer may incorporate a Penning trap (Fourier transform ion cyclotron resonance), Paul trap or the Kingdon trap. The Orbitrap, introduced in 2005, is based on the Kingdon trap. Other types of mass spectrometers may also use a linear quadrupole ion trap as a selective mass filter. Penning ion trap Mass Analyzers (Mass Spectrometry) Chemistry LibreTexts Quadrupole Ion Trap Mass Analyzers. This analyzer employs similar principles as the quadrupole analyzer mentioned above, it uses an electric field for the separation of the ions by mass to charge ratios. The analyzer is made with a ring electrode of a specific voltage and grounded end cap electrodes. The ions enter the area between the ...

Download. Quadrupole Ion Trap an overview | ScienceDirect Topics The quadrupole ion trap mass analyzer consists of the ring electrode, the entrance endcap electrode, and the exit endcap electrode. These electrodes form a cavity in which ions are trapped and analyzed. The endcap electrodes have a small hole in their centers that allow ions to either enter or exit the trap. Quadrupole Ion Trap an overview | ScienceDirect Topics D Ion Trap Mass Spectrometer. The popularity of the quadrupole ion trap has its roots in the discovery and development of the mass selective axial instability scan, for which G. C. Stafford, Jr. was awarded the 2001 ASMS Distinguished Contribution in Mass Spectrometry Award [45]. Stafford s discovery of the mass selective instability mode ...
