ion trap [′ī‚än ‚trap] (electronics) An arrangement whereby ions in the electron beam of a cathode-ray tube are prevented from bombarding the screen and producing an ion spot, usually employing a magnet to bend the electron beam so that it passes through the tiny aperture of the electron gun, while the heavier ions are less affected by the magnetic field and are trapped inside the gun. A metal electrode, usually of titanium, into which ions in an ion pump are absorbed. How to thank TFD for its existence?

With those, he adds, scientists will probably duplicate and then surpass the feats of quantum manipulation already attained with conventional ion traps. 25-[micro] m pore size), a direct breath sampling interface (glow discharge ionization source), and a compact ion trap mass spectrometer (ITMS) that is capable of operation in the full tandem (MS/MS) mass spectrometric mode (40,45-48). The newly released hybrid linear ion trap time-of-flight mass spectrometer (LIT-TOF MS) is the first commercially available instrument to combine the reproducibility and robustness of a true splitless nanoflow LC with the sensitivity and mass accuracy of a linear ion trap time-of-flight mass spectrometer. |
