The multiple relationships provided by the public database allow the user to use both the proprietary and public data to find a relationship with a potential client. Thereafter, the substrate is removed from the chamber. The invention furthermore relates to a corresponding diagnostic device, a corresponding diagnostic system, as well as a computer program is also described.
