The Orbitrap: a new mass spectrometer.
Research areas such as proteomics and metabolomics are driving the demand for mass spectrometers that have high performance but modest power requirements, size, and cost. This paper describes such an instrument, the Orbitrap, based on a new type of mass analyzer invented by Makarov. The Orbitrap operates by radially trapping ions about a central spindle electrode. An outer barrel-like electrode...
متن کاملHost–Guest Chemistry in the Mass Spectrometer
The study of host–guest chemistry in the gas phase has been pursued systematically only in the last 5 years, after sporadic interest in the 1980s, despite extensive investigation of this chemistry in the condensed phase and the success encountered in several Ðelds of application. Most gas-phase studies have been performed under the controlled conditions that can be achieved inside a mass spectr...
متن کاملMass-spectrometer study of the rare gases.
A stu dy of the appearance potentia ls and isotope abundance of tbe rare gases has been made \yith a Consolidated Engin eering Corp. mass spectrometer as a check on the operation of th e instrument. The res ults a re comparable to previously publi shed data. In add ition, some nell' experimental value of ionization poten tials have been obtained. Generally, good agreement of the isotope ab unda...
متن کاملSTUDIES with the AEROSOL MASS SPECTROMETER
Fast time-response of the Aerodyne Aerosol Mass Spectrometer (AMS) makes it a well-suited instrument for ambient field measurements. On the other hand, laboratory chamber experiments provide the opportunity to study a specific system in a more controlled environment. The goal of this thesis is to provide a summary of laboratory and field measurements using the AMS. During laboratory chamber pho...
متن کاملMacromolecular ion accelerator mass spectrometer.
We present a newly developed macromolecular ion accelerator mass spectrometer that combines a dual-ion-trap device and a macromolecular ion accelerator (MIA) to achieve the capability of analyzing samples with a mixture of large biomolecules. MIA greatly increases detection efficiency. The dual ion trap includes a quadrupole ion trap (QIT) and a linear ion trap (LIT) in tandem. The dual ion tra...
