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.

ENVIRONMENT

  • Empower

PROCEDURE

  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

  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).

  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!
