Exemplary embodiments provides computer-implemented methods, mediums, and apparatuses that provide an architecture for supporting event notifications in an analytical chemistry system. The notifications architecture allows notifications to be sent within and outside the analytical chemistry system. It supports notifications provided by disparate devices and applications of the analytical chemistry system and allows the notifications to be sent on a variety of different delivery channels in a unified and consistent way. The architecture is easily extensible to support new types of notifications and new delivery channels. The architecture supports stateful notifications, allowing the read/unread status of the notifications to be displayed. Furthermore, the architecture can leverage existing events to generate notifications, which allows events to serve multiple purposes in the analytical chemistry system and therefore reducing the amount of messages and processing that needs to be done in the system.
