Tip #88: Creating Custom Fields in Empower (Part 7)
Welcome back to Get Empowered! In the last Empower tip-of-the-week post for Empower CDS Software, we learned how to modify a Custom Field (Tip #87).
Creating Custom Fields in Empower:

- #87: How to modify a Custom Field
This week, we will learn how to create a Result Custom Field (Part 7).
In Tip#85, we learned how to create a Peak Custom Field. A Peak Custom Field is a user-defined calculation pertaining to a peak or peaks within the chromatogram. A Peak Custom Field might produce multiple results for the chromatogram. A Result Custom Field is a user-defined calculation pertaining to all of the peaks in the chromatogram and, as a result, produces one result for the entire chromatogram. Today we will create a Result Custom Field to calculate the average peak width of the peaks in our chromatogram. This information is helpful when creating or fine-tuning a processing method.
Let’s get started.
Step 1
Launch the new Custom Field wizard and on the Data and Type Selection screen select Result for the field type and Real for the data type (Figure 1).
Step 2
On the Source Selection screen, the data source defaults to Calculated. Whenever you select either field type Peak or Result, Empower understands that you want to make a calculation (Figure 2).
Step 3
On the Formula Entry screen, scroll to the right in the Operations area, locate AVE( and double-click to add it to the Field area (Figure 3).
Step 4
Scroll to the right in the Fields section and locate Width. Double-click Width to add it to the Field area. Finally, add the right parenthesis character ) to close the equation (Figure 4).
Step 5
On the Numeric Parameters screen, set the desired width (Figure 5).
Step 6
Once the Custom Field has been saved, open the project, process a Sample Set, select a result, and open Review. A Result Custom Field will be visible in the Results window within Review. From the Windows menu, select Results (Figure 6).
Step 7
The individual peak widths are seen in the Peaks table and the Average Peak Width is seen in the Chromatogram Result table (Figure 7).
It’s that easy!
What if we want to calculate the average peak width for certain types of peaks? I will cover that topic in the next Tip.
Final Notes: This procedure can be followed using the QuickStart or Pro interface.

Next week in Empower Tip #89 – We’ll continue our series on Custom Fields and learn how to modify a Custom Field that applies to specific samples and/or specific peaks (Part 8).
