Welcome back to Get Empowered! In the last Empower tip-of-the-week post for Empower Chromatography Data Software, we learned how to use the average area of replicate injections of a sample to quantitate the sample (Tip #98).

This week, I want to share another great question I received.
Q: When do you need batch processing for Custom Fields? And can I generate results in Review with my Custom Fields?
A: Depends on the type of Custom Field.
In this tip, I will demonstrate when to batch process the sample set to get results from Custom Fields (Part 17).
Let’s get started.
- If you recall from Tip #84 & Tip#85, we discussed how to calculate Percent Label Claim which is a relatively simple Peak Custom Field (figure 1).
- In this example, take the Sample Set into Review, open the Processing Method and review the samples one by one. The Percent Label Claim is calculated for the samples (figure 2).
- In last weeks’ Tip (Tip#98), we calculated the ‘average area’ of peaks over replicate injections of a sample. This is an Intersample Calculation with summary function ‘AVE’ (figure 3).
- In this example, we need to ‘batch process’ the Sample Set with a Summarize Custom Field line at the end of the Sample Set so that the summary calculation works properly (figure 4).
It’s that easy!
Final note: This procedure can be followed using the QuickStart or Pro interface.
