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.
