Here is another frequently asked question regarding Custom Fields:

Q: How can you report the pressure or temperature at a certain time point within the chromatogram?

A: Assuming you have collected the pressure or temperature channel, it’s quite easy to do.

In this tip, I will show you how to report the pressure and temperature at a certain time point within a chromatogram (Part 14).

Let’s get started.

Step 1

Create a Peak Type Custom Field, ‘data type real’. There is a field called ‘YValue’ which will report the YValue at a time point within a channel. Once selected, enter the time value (in minutes) and close the square bracket (Figure 1).

Figure 1

Step 2

Include the ‘channel name’ in the Method Set with a Processing Method so that the channel is processed and the value is determined (Figure 2).

Step 3

I’ve applied the Method Set to an injection and the value, in this case, ‘pressure’ is displayed (Figure 3).

It’s that easy!

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