Introduction: the NeSSI generations

Marketing

• Publications– increasing number of articles and reviews of NeSSI

• Media pack– media pack prepared

• Wiki– we’re in the world’s encyclopaedia

• History– we’re so old that we have an auto-biography

• And our home library is still at the CPAC site

The big issues

Gen I: fluid handling• Demonstrating the value proposition

Generation II: networked connectivity• Commonality of network design / avoiding bus wars• Establishing and maintaining comms standard• Establishing and maintaining a data standard

Topics for this evening’s workshop

Generation III: microanalytical systems• Getting the momentum of an initiative
