The invention relates to a method for dosed delivery to a carrier medium of at least one active substance, by determining a desired volume flow of the active substance and delivering the thus determined volume flow uniformly to the carrier medium, wherein the volume flow of active substance is generated by means of a controlled volume displacement, for instance an injection. Control can take place by pulse-form signals. The invention also relates to a device for performing the method with a transport conduit (2) for the carrier medium, at least one container (8) for an active substance connected to the transport conduit (2), and a cylinder (34) connecting the container (8) to the transport conduit (2) and having a driven piston (35) movable therein. The drive can be formed by a linear motor (36). <IMAGE> |
