• Swagelok committed to analytical instrumentation for over 50 years

• Our response to NeSSi and subsequent work have helped define 1st generation miniature modular sample systems

• We are continually developing “fit-for-purpose” 1st generation components

• We are ready to move on to defining and developing 2nd generation components

Evolution of Modular Sample SystemsEvolution of Modular Sample SystemsEvolution of Modular Sample SystemsEvolution of Modular Sample Systems

• 1st Generation NeSSi – miniature modular achieved– ISA SP76 interface standard – Commercially available control solutions– Functional downmount components – Systems successfully installed – Benefits are being realized

• 2nd Generation NeSSi – Smart is next– Plug-n-play devices, integrated with S.A.M.– Multi-drop sensor bus communications– Self-diagnosing sample systems– Configurable device personalities– Multi-variable transducers
