The Diamond Hydride™ column comes with a package insert that describes initial conditioning steps that should be done when you first receive the column.

“Washings” usually only need to be done once to condition the column before use but that will depend on what you inject on to it and how well you prepare and filter your samples. Under normal HPLC conditions, these columns do not need to be conditioned on a continual basis.
