Abstract

A method of initiating an operation in dependence on the combined mass of an element and matter which is in or on the element can be used to remove matter which has accumulated on the rotor of a centrifuge. A substantial change is effected in the speed of rotation of the rotor and the rate of change is then measured. The operation is initiated when the rate of change is above or below a predetermined value.
