* Thermo Fisher Scientific--The LTQ Velos features a new dual pressure trap design and API source; making it the fastest and most sensitive ion trap MS.
Hitachi's systems as well as Varian's 500-MS LC Ion Trap, which was making its first Pittcon appearance, and the Waters's announcement of software agreements with Thermo Electron and Bruker Daltonics' for LC/MS (see page 7), illustrate how the LC battles extend to LC/MS, as such systems comprise an important part of the LC market and can drive LC sales.
Bruker Daltonics' HCrultra ion trap has improved speed and sensitivity over the previous generation HCT.
Its sensitivity, ion capacity and mass resolution are comparable to those of traditional ion trap mass spectrometers.
The ion trap LC-MS-MS can also be used for screening, as well as to confirm presumptive-positive screening results from LC-single-quadrupole MS.
The heart of an ion trap mass spectrometer, such as the LCQ Deca XP from San Jose, Calif.-based Thermo Finnigan, is about the size of a tennis ball.
Bruker Daltonics introduced the HCTultra ion trap MS, Broker's premier ion trap model.
The ion trap's ability to generate multiple stages of MS delivers the information needed to unambiguously characterize compounds and identify structures.
The LTQXL linear ion trap mass spectrometer features electron transfer dissociation (ETD), an ion fragmentation technology that provides new peptide structure information not available from conventional dissociation methods.
A version for Agilent's Time-of-Flight MS will be available by mid summer and a version for the ion trap MS is expected by year end.
Two mass spectrometers described elsewhere in this issue - a speciated isotope dilution mass spectrometer from Duquesne Univ., Pittsburgh, and Quistor, an ion trap MS with a plasma-ionization source from DOE's Pacific Northwest National Lab, Richland, Wash., and Finnigan Corp., San Jose, Calif.
