Procedure
- To display the associated precursor scans (precursor before and after the MS/MS scan), select the MS/MS Spectrum Info icon,
, in the upper-left corner of the Field Chooser.
- The Field Chooser menu opens.
- From the Field Chooser menu, select Master Scan.
- To display Associated PrSMs, Proteoforms, and so on, select the down arrow next to Show Associated Tables,
.
Column | Description |
---|---|
File | The .raw data file name. |
RT [min] | Retention time of the MS/MS scan (in minutes). |
First Scan | First precursor scan associated with this MS/MS scan. |
Activation Type | Activation type used to generate ions in the MS/MS scan. |
NCE[%] | Normalized Collision Energy applied if HCD is used. |
# PrSMs | Number of PrSMs that this MS/MS scan supports. |
Isolation Interference [%] | Measure of co-isolated precursor interference. |
Ion Inject Time [ms] | How long ions were collected prior to analysis. Shorter times indicate a more abundant signal. |
m/z [Da] | Observed mass. |
Mass [Da] | Monoisotopic observed mass. |
Theo. Mass [Da] | Theoretical mass based on matched proteoform from database. |
ΔMass [ppm] | Observed theoretical mass error in parts per million. |
ΔMass [Da] | Observed theoretical mass error in Daltons. |
Matched Ions | Number of matched fragment ions supporting the PrSM. |
