Abstract (en)
[origin: EP2737949A2] The system (100) has a separation element (30) for separating stored substance (20) from fluid (10) in an initial configuration, where the stored substance is dispensed to the fluid by actuation upon the element in a continuously metered manner discretely with a time delay or in multiple stages over a predefined period of time and the actuation comprises physical or chemical stimulation of the element. The element completely surrounds the stored substance in the initial configuration, where the actuation ensures permeability of the element for the stored substance. The stored substance is selected from a group consisting of liquid, gas, particle and solid material. The physical stimulation is external force, centrifugal force and hydrostatic pressure or electrical energy. The chemical stimulation is a pH value, solubility, surface size and temperature of the stored substance, the element and the fluid. Independent claims are also included for the following: (1) a cartridge (2) a method for producing a component.
