Tip #237: Creating a Process Only Sample Set in Empower
Welcome back to Get Empowered! In the last Empower tip-of-the-week blog for Empower Chromatography Data System, we learned how to drill down in a Sample Set within Review and stay on the same channel throughout (Tip #236).
In this week’s tip, we will learn how to create a Process Only Sample Set.
There are times when taking previously acquired data and processing them as a group is desirable, particularly when doing content uniformity or dissolution. You can combine Sample Sets, Injections or Channels into a Process Only Sample Set, then process and generate a Result Set.
Let’s get started.
In this example we want to create a Process Only Sample set using previously acquired channels of data from a stability study. Very specifically, we want to combine channels from weeks 9 and 10 which live in two different Sample Sets.
Highlight the Sample Sets of interest, right click, and select ‘View As, Channels’ (figure 1).
Highlight the channels of interest, right click, and select ‘Create Process Only Sample Set’ (figure 2).
Enter a name for the Process Only Sample Set and click ‘OK’ (figure 3).
A window opens, similar to the Alter Sample window. Add any needed information and/or make any necessary changes. Save all changes (figure 4).
You will be required to enter a comment (figure 5).
On the Sample Sets tab of the project, create a View Filter that contains the ‘Sample Set Type’ field. Now you can see which Sample Sets were acquired in the normal fashion and which ones are Process Only Sample Sets (figure 6).
Process the ‘Process Only Sample Set’ and bring the Result Set into Review. It now looks like a typical Result Set (figure 7).
You can report the Result Set as well. Here you see the overlay of the chromatograms (figure 8).
View summary tables for ‘Peak Area’ and ‘Retention Time’ summarizing the results (figure 9).
It’s that easy!
Final Note: You can use either the Pro or QuickStart interface for this tip.
