Tip #89: Creating Custom Fields in Empower (Part 8)

Welcome back to Get Empowered! In the last Empower tip-of-the-week post for Empower CDS Software, we learned how to create a Result Custom Field (Tip #88).

Creating Custom Fields in Empower:

  • #82: The basic steps on creating a Custom Field
  • #83: How to create a Custom Sample Set Field
  • #84: How to create a Component Custom Field
  • #85: How to create a Peak Custom Field
  • #86: How to copy a Custom Field from one project to another
  • #87: How to modify a Custom Field
  • #88: How to create a Result Custom Field

This week we will learn how to modify a Custom Field that applies to specific samples and/or specific peaks (Part 8).

Please refer back to Tip #87 which covered how to modify an existing Custom Field.

Let’s get started.

Step 1

Let’s first review the result from Tip #88. The average peak width was calculated based on all peaks in the chromatogram, which includes Found and Unknown peaks (Figure 1).

Step 2

Let’s modify the Custom Field to calculate average peak width for only the Found peaks. Go to the properties of the project, Custom Fields tab, Highlight the Custom Field and click Edit. (Note: the Sample Type and Peak Type fields both default to All) (Figure 2).

Step 3

Click and view the choices in the drop-down list for Sample Type. We could have this calculation done for only standards or only controls (Figure 3).

Step 4

Click and view the choices in the drop-down list for Peak Type. In this case, we select Founds so that Empower makes the calculation for only Found peaks (Figure 4).

Step 5

Once you make the choice, a warning message appears telling you that the Custom Field will be calculated for only the selected peak type. Click OK (Figure 5).

Step 6

Once we reprocess our data, we see the average peak width value is different now that we have excluded the Unknown peak from the calculation (Figure 6).

It’s that easy!

 

Final Notes: This procedure can be followed using the QuickStart or Pro interface.
