Smart Components for Miniature Modular Sample Systems A Connectivity and Communication Solution Richard A. Ales David M. Simko John J. Wawrowski Swagelok Company, Solon, Ohio IFPAC San Diego, CA 1/23/2002
BackgroundBackground Swagelok committed to analytical instrumentation for over 50 years Our response to NeSSi and subsequent work have helped define 1 st generation miniature modular sample systems We are continually developing “fit-for-purpose” 1 st generation components We are ready to move on to defining and developing 2 nd generation components
Evolution of Modular Sample Systems 1 st Generation NeSSi – miniature modular achieved –ISA SP76 interface standard –Commercially available control solutions –Functional downmount components –Systems successfully installed –Benefits are being realized 2 nd 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
