Through an agreement with Zoex Corp., JEOL's AccuTOF GCV 4G high-resolution time-of-flight mass spectrometer
system now comes with Zoex's two-dimensional gas chromatography (GCxGC) technology.
An electric field is applied to lift these ions into the time-of-flight mass spectrometer
, which separates them according to their mass and charge, displaying the results as a series of peaks or spectra which correspond to different proteins and peptides expressed by the organism.
(1) The particulate matter in the resulting mixture was sized using a scanning mobility particle sizer, and its composition was examined using a time-of-flight mass spectrometer
Miniaturized time-of-flight mass spectrometer
for peptide and oligonucleotide analysis.
A compilation of 28 application notes describes analyses performed using the AccuTOF time-of-flight mass spectrometer
with the DART ion source.
Micromass scientists presented preliminary results for a quadrupole orthogonal time-of-flight mass spectrometer
equipped with a MALDI source.
The mass spectrum of the individual sub-micron particles will be obtained with a laser-ablation time-of-flight mass spectrometer
currently under construction (Hastie and Mozurkewich).
The time-of-flight mass spectrometer
being developed can fit into a package the size of a shoebox.
This acquisition gave LECO Meridian's Fast Chromatographic Detector, a time-of-flight mass spectrometer
The venture will combine the technology of PE Sciex's QSTAR Time-of-Flight mass spectrometer
and Protana's expertise in protein microcharacterization and systems integration, in hopes of improving the sensitivity and reliability in protein sequencing.
But perhaps even more interesting than these introductions, are the systems rolled out recently that use a time-of-flight mass spectrometer
rather than a quadrupole or ion trap.
