Sentence examples for fragmentation scans from inspiring English sources

For DIA, one MS1 scan (R = 70,000; mass range from 400 to 1200 m/z) was followed by 32 MS/MS full fragmentation scans (R = 35,000) using an isolation window of 26 m/z (0.5 m/z overlap between consecutive windows).

Data sets were acquired in a data-dependant manner where each analytical full scan (MS, 200 2,000 m/z units range) was followed by three fragmentation scans (MS/MS) that targeted the three most abundant ions from the full scan.

Sequence coverage maps derived from consecutive ETD and CAD fragmentation scans are shown in Figure 1 for three representative proteins.

Additionally, for fragmentation scans without an associated precursor, the large window 100 000 Da precursor search was performed.

Autopilot applies Xtract with a 3 signal/noise cutoff to full precursor scans, SIM scans, and fragmentation scans.

The resolution settings were 60 000 and 30 000 for precursor and fragmentation scans, respectively, at 400 m/ z.

The three most abundant signals of a survey scan (400 1300 m/z range, 0.87 s scan time and 0.13 s inter-delay) were selected by charge state, and collision energy was applied accordingly for sequential MS/MS fragmentation scanning (50 2000 m/z range, 0.9 s scan time, 0.1 s inter-delay).

This first-in, first-out queue supplies a new fragmentation scan definition to the instrument as soon as the data from the previous scan is returned.

It should be noted that while ammonium adducts were the predominant form of intact TAG ions in the MS scan (Fig.  1a), the relative abundance of the sodium adduct is enhanced in the all-ion fragmentation scan (Fig.  1b).

MS scans and precursor isolation-fragmentation scans were performed across the range of 40 350 Da.

For data evaluation, adducts and isotopes were taken from the scan event without fragmentation and fragments from the scan event with fragmentation.
