7890A FID Column baking? conditioning? Method

Use GC7890A, FID.
I want to bake it again because the column is contaminated.

I have a question.

1. Do I have to separate the column from the detector?
2. Do I need to connect the column to the detector?

※ If you need to disconnect the detector, why?

- I used a translator because I'm Korean. Please excuse me.
