Table 6-10 IDA Criteria (continued)
Description
Label
Select the check box to use the IDA: Inclusion List criteria. Click the link to open the IDA:
Inclusion List dialog and edit the criteria.
Candidate ions that are on the inclusion list and meet the inclusion list criteria are
preferentially selected for MS/MS.
• Compound name: The name of the candidate ions. The name can include any characters
and does not have to be unique. The compound name is recorded in the file information.
This field can be left blank.
• m/z (Da): Type the
m/z
value for the ions on which MS/MS is preferentially performed.
• Retention time (min): Type the LC retention time for the ion of interest. If the ion is
detected at the specified retention time, it is preferentially selected for MS/MS. Typing
a value of 0 indicates that the ion is preferentially considered throughout the acquisition.
• Retention time tolerance (+/-sec): This value is the +/- time window around the specified
retention time. Tolerance helps to account for any drifts in the LC retention time. If the
ion on the inclusion list is detected in the window around the specified retention time,
then it is preferentially selected for MS/MS.
• Intensity (cps): Specify the intensity threshold for the ion on the inclusion list. If the
candidate ion surpasses the threshold (in cps), then it is preferentially selected for MS/
MS.
Inclusion List
Select the check box to use the IDA: Exclusion List criteria. Click the link to open the IDA:
Exclusion List dialog and edit the criteria.
Candidate ions that are on the exclusion list are not selected for MS/MS at the retention
time specified.
• Compound name: The name of the candidate ions. The name can include any characters
and does not have to be unique. The compound name is recorded in the file information.
This field can be left blank.
• m/z (Da): Type the
m/z
value for the ions on which MS/MS is not performed.
• Retention time (min): Type the LC retention time for the ion of interest. If the ion is
detected at the specified retention time, then it is not selected for MS/MS. Typing a value
of 0 indicates that the ion is not considered throughout the acquisition.
• Retention time tolerance (+/-sec): This value is the +/- time window around the specified
retention time. Tolerance helps to account for any drifts in the LC retention time. If the
ion on the exclusion list is detected in the window around the specified retention time,
then it is preferentially excluded for MS/MS
