Tip #206: Filtering the Control Chart for certain components

The previous tip (Tip #205) explained how to add a Purity Plot to a Report Method.

This tip explains how to filter Control Charts.

ENVIRONMENT

  • Empower

PROCEDURE

  1. In this chromatogram, you have three peaks, two of which have a lower limit set for the USP Plate Count.

  2. The Report Method displays a Control Chart for each peak. The Uracil Peak is a "void volume marker", and we want to filter that peak out of the report.

    There is no Peak level filtering available in the Summary Plot, but there is a workaround. By creating a composite group that includes the Summary Plot, you enable peak level filtering.
     
  3. Expand "Drawing Objects", and then expand "Rectangles". Double-click the white rectangle to add it under the Summary Plot.

  4. Control+click both groups, and then, from the Edit menu, select Group.

    (Alternatively, you can select Composite Properties from the Edit menu.)

  8. Click in the "Condition 1" field, which opens the Create a Condition dialog. Select "Not Equals", type the name of the peak in the field to the right, and click OK.

  10. Click OK to the Data Filter Conditions and the Composite Properties. In Preview, you see the Uracil peak was filtered out of the report and the white rectangle is invisible.
