2) novel technologies that incorporate new ionization sources, sample injection methods or mass analyzers.
Keith Clemenger was performing polarizability measurement Winston Saunders was optimizing the quadrupole mass analyzer for larger sizes and de Heer was measuring magnetic properties of small alkali clusters.
Also introduced by Thermo at ASMS was the Exactive benchtop LC/ MS system, which is based around the Orbitrap mass analyzer, in contrast to Thermo's LTQ-Orbitrap and LTQ-FT, the Exactive is not a tandem system, which greatly lowers its price, but it can still provide MS/MS.
WIL Research is the first CRO to use the Q-Exactive high-resolution mass analyzer to support discovery PK.

Users can chose from ion sources (chemical ionization, electrospray ionization, and MALDI), different mass analyzers (time-of-flight, quadrupole, quadrupole ion trap, linear quadrupole ion trap, orbitrap, and more), and different detectors.
The LTQ Orbitrap Velos combines Thermo's Orbitrap mass analyzer with a new high-energy collisional dissociation cell and dual pressure trap technology for ultra-high resolution and accurate mass data.
One vendor that is on the verge of entering the portable GC/MS market is Microsaic, which has developed a quadrupole mass analyzer on a chip that can be easily configured as a suitcase-sized GC/MS; it has been shown in such a configuration in the company's ChemPack instrument.
The CIS ionizer produces ions by electron impact directly at process pressure, while the rest of the mass analyzer and the filament are kept under high vacuum.
The LTQ Orbitrap XL, developed by Thermo Scientifc, is based on the fast and sensitive LTQ XL[TM] linear ion trap mass spectrometer and the Orbitrap mass analyzer.
The following are the most important aspects of the mass spectrometer: The device consists of four main components: a) HPLC system, b) CryoESI source, c) ion mobility unit, d) qTOF mass analyzer.
Mass spectrometers with more than one mass analyzer (tandem MS or MS-MS) provide the next higher level of confidence in identifying banned substances.
