Changing analyte details

On the METHOD tab, you can make the following changes on the Analytes page.
  1. To edit the analyte details, in the upper-right corner, click .
  2. To change the order (ascending or descending) in which the analyte names appear, in the Analyte Name column header, click .
  3. To change information in a cell, click the cell, and then specify the details.
    Tip: You can use the Tab key to edit the subsequent cells.
  4. To add a new row, click .
  5. To delete a row, select the row, and then click .
  6. To change the internal standard details on the Analytes tab, use the Linked Internal Standards drop-down menu.
    Note: Internal standards that are linked to another internal standard are not available for selection (see "Adding internal standard information", step 5).
  7. To change the reference compound details, use the Calibration Reference Compound drop-down menu.
    Note: You cannot choose the internal standard as a calibration reference compound.
  8. To add a new precursor mass on the Analytes tab, in the Precursor Mass cell, click .
  9. To add a new product mass on the Analytes tab, in the Product Mass cell, click .
  10. To update the retention times for all analytes, based on the detected retention time in the quan reference injections, on the Analytes tab, click .
    Note: The "Update expected retention time" option is enabled when quan references injection is set.
  11. To modify groups on the Analytes tab, select the rows of the analyte group, click , type a group name, and then click Assign or Clear.
  12. To edit the details on the Levels tab, specify the value in the cells.
  13. To change processing information on the Processing tab, see "Adding analyte processing information", step 3.
  14. To turn the peak parameters on or off and specify the value to the relevant columns on the Integration tab, turn on the Force Peak toggle for the analyte you want, and then specify the value in the required cells.
  15. To edit information on the Ion Ratios tab, perform steps 2 through 5.
  16. To turn the analyte on or off as a system suitability injection, on the System Suitability tab, use the System Suitability toggle.
    Note: When System Suitability is turned on, you can also select or clear the selections.
  17. To change the minimum peak area on the System Suitability tab, in the Minimum Peak Area cell, specify the value.
  18. To specify the R-square value to the analytes on the Flagging tab, in the R2 Value column, specify the R-square value as less than 1.0.
    Tip: For a better calibration line, Waters recommends aiming for a higher value, as close to 1.0 as possible.
    Note: Ensure that the R Squared Value and R Squared Value (Method) rules are turned on to raise any exceptions. If you do not specify a value, you will not see any exceptions for that analyte.
