Sentence examples for mass spectrometer collected from inspiring English sources
The mass spectrometer collected data in a data-dependent fashion, collecting one full scan in the Orbitrap at 120,000 resolution followed by 20 collision-induced dissociation MS/MS scans in the dual linear ion trap for the 20 most intense peaks from the full scan.
We purified histone H2B from acid-extracted histones using C18-based reversed-phase chromatography, then infused the purified H2B directly into the mass spectrometer and collected spectra to determine the intact masses of the H2B isoforms.
We tested the tandem mass spectrometer for collecting precursor ion spectra of all the ions stored in the trap and demonstrated that we can selectively detect a phosphopeptide in a mixture of non-phosphorylated peptides.
The flexibility of the modular approach allows us to use the strengths of each mass spectrometer for collecting additive information about a sample in a data-dependent manner.
This process enabled the mass spectrometer to collect data from less intense precursors that were not acquired during the first analysis.
Electrospray mass spectrometer data were collected between 12 and 25 min post injection, and deconvoluted using MaxEnt1 software (Waters).
Samples were directly injected into a Finnigan TSQ Quantum triple quadrupole mass spectrometer, and data was collected in negative ionization mode.
MS spectra were collected in the Orbitrap component of the mass spectrometer and MS/MS spectra was collected in the LTQ.
While the autosampler and one of the HPLC pumps were used for the SPE cleanup of one sample, the 10-port switching valve, the second HPLC pump, and the mass spectrometer were used to collect data from the previous sample (Ye et al. 2006).
Mass spectral data were collected with a 10 minute gradient on a Thermo LTQ-Velos Orbitrap mass spectrometer (Thermo Fisher, San Diego, CA) to collect data from mass/charge ratio (m/z) 85 to 2000 in a positive ionization mode.
Open image in new window Fig. 5 Mass spectrometer fragmentation pattern of products collected upon ethanol photoreaction under UV excitation for a previously exposed Au Pd/TiO2 to ethanol for 4 min at 10−7 torr (this exposure was found to ensure surface saturation based on monitoring of desorption products).
