Tip #97: Creating Custom Fields in Empower (Part 15)

Welcome back to Get Empowered! In the last Empower tip-of-the-week post for Empower Chromatography Data Software, we learned how to report pressure at a certain time point in the chromatogram (Tip #96).

This week, I want to share a follow-up question I received from last week’s tip (Tip #96):

Q: How can I report the maximum pressure (or other channel, such as temperature) during a chromatographic run?

A: This is important to know because you do not want to exceed the pressure recommendations from the column manufacturer.

In this tip, I will show you how to report the maximum pressure during a chromatographic run (Part 15).

Let’s get started.

Step 1

Create a Peak Type Custom Field, ‘data type real’. Working with ‘YValue’ as we did in the last tip, simply enter ‘Retention Time’ into the brackets rather than a specific retention time (Figure 1).

Step 2

Create a Result Type Custom Field, ‘data type real’. Use the MAX function to report maximum pressure (Figure 2).

Step 3

You’ll notice that I applied the Method Set to an injection and the pressure at various time points is displayed (Figure 3).

Step 4

In the Results window, view the maximum pressure in the Chromatogram Result table (Figure 4).

It’s that easy!


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