Abstract

The invention discloses a method for individually assessing the cleanness of at least one of an upper (2) and a lower (3) bed support in a process column (1). The method comprises the steps of: a) providing a process column (1) comprising an upper (2) and a lower (3) bed support, a column chamber, a movable adaptor (5), an upper outlet (6) and a lower outlet (7); b) conveying liquid through one of the lower (3) and upper (2) bed supports, e.g. by moving the adaptor (5) downwards at a predetermined rate with one of the upper and lower outlets closed and the other open to force liquid through one of the lower and upper bed supports, and; c) measuring the differential pressure over the bed support through which liquid passes.
