Viewing peak integration exceptions

To view peak integration exceptions:

  1. On the OVERVIEW tab, in the sidebar, click Peak Integration.
  2. To edit peak integration information, in the upper-right corner, click .
  3. To apply or remove the peak integration exceptions Injection RT, Ion ratio, Quan Ion Not Detected, Analyte RT, and Manual changes, use the exception filter at the top of the page.
    Tip: If the filter is active, a check mark appears on the filter. The filter also displays the number of exceptions on it.
  4. To view or remove sample types Solvent, Blank, Standard, Quality Control, and Unknown, use the Sample type filter at the top of the page.
    Tips:
    • If the sample type is present, a check mark appears on the filter.
    • Each sample type has a dedicated shape and color.
  5. To view by analyte or internal standard, use the drop-down menu in the Analytes box.
    Tip: To view an individual analyte or internal standard, select the analyte or internal standard from the list.
  6. To ignore all exceptions for an analyte or internal standard, click the red exception number next to the name, select Ignore all Injection RT exceptions for this analyte, Ignore all Ion Ratio exceptions for this analyte, Ignore all Quan Ion Not Detected exceptions for this analyte, Ignore all Analyte RT exceptions for this analyte, or Ignore all Manual Change exceptions for this analyte, and then click OK.
  7. To ignore all exceptions for an analyte or internal standard from the graph, click the red exception number next to the name, select Ignore all Injection RT exceptions for this analyte, Ignore all Ion Ratio exceptions for this analyte, Ignore all Quan Ion Not Detected exceptions for this analyte, Ignore Analyte RT exception, or Ignore all Manual Change exceptions for this analyte, and then click OK.
    Note: To add exceptions again, click the gray exception number on the graph, clear the selections, and then click OK.
  8. To change the lift off or touch down % for the integration parameters, expand Integration settings, specify a value in the Lift Off or Touch Down box or both, and then click Apply.
  9. To optionally lock and unlock all Y (intensity) axes to the same absolute scale as a selected peak, select the peak, and then, at the bottom of the page, use the Lock and Unlock toggles.
  10. To change the size of plots, at the bottom of the page, use the Small, Medium, and Large toggles.
    Tips:

    The QUAN Review application is useful for detecting common failure modes. Only the medium and large viewing modes are suitable for detecting peak quality issues. The viewing modes are defined as follows:

    • Small is useful for a quick overview of the result set—for example, to see if expected peaks were detected consistently at the correct retention time across the injection series, indicating that the method parameters are suitable, before you investigate the data set more closely.
    • Medium or Large is useful for assessing detected peaks for correctness of integration, retention time, and shape.
  11. To view the injections on the next page or previous pages, in the lower-right corner, use the arrows.
  12. To save your changes, in the upper-right corner, click .
  13. To discard the changes, click .
