When doing the wipe test on an ECD, do you just disconnect the column from the makeup gas adapter, or do you actually drop the makeup gas adapter and wipe the outside of that?

The instructions here aren't real clear, though the picture looks like it has the adapter disconnected. https://www.agilent.com/cs/library/user ... 0-3586.pdf

Looks like it - the way I've done it in the past (not on uECDs though) has been to just wipe around the ferrule/nut without disconnecting the column.
