Miniaturized Linear Wire Ion Trap Mass Analyzer.
We report a linear ion trap (LIT) in which the electric field is formed by fine wires held under tension and accurately positioned using holes drilled in two end plates made of plastic. The coordinates of the hole positions were optimized in simulation. The stability diagram and mass spectra using boundary ejection were compared between simulation and experiment and good agreement was found. Th...
متن کاملMultiplexed rectilinear ion trap mass spectrometer for high-throughput analysis.
A multichannel mass spectrometer based on the rectilinear ion trap (RIT) analyzer was designed and constructed for simultaneous high-throughput analysis of multiple samples. The instrument features four parallel ion source/mass analyzer/detector channels assembled in a single vacuum chamber and operated using a common set of control electronics, including a single rf amplifier and transformer c...
متن کاملRapid hydrocarbon analysis using a miniature rectilinear ion trap mass spectrometer.
A miniature ion trap mass analyzer was applied to the analysis of traces of hydrocarbons and simple heteroatomics in the vapor phase and in aqueous solution. Vapors of acetone, acetic acid, acetonitrile, benzene, butanethiol, carbon disulfide, hexane, dichloromethane, naphthalene, toluene and xylenes were detected and quantified using solid sorbent trapping and, in some cases, by passage throug...
متن کاملCo-occurrence of boundary and resonance ejection in a multiplexed rectilinear ion trap mass spectrometer.
A method is reported for evaluating ion trap mass analyzers by selection of operating conditions under which both boundary and resonance ejection peaks occur in a single mass scan. The choice of frequency and amplitude of the auxiliary waveform applied for resonance ejection can be such as to produce a resonance ejection mass spectrum with unit resolution or, under selected conditions, signals ...
متن کاملIon-Trap Quantum Computation
Quantum computation requires a very special physical environment. Numerous operations must be performed on the quantum states of the qubits (or quantum bits) before those states decohere, or lose the interlocking phase relationships that give quantum computation its power. Thought to be an unavoidable outcome of the interaction between the quantum state and the environment, decoherence threaten...
