What is NeSSI™? • Industry-driven effort to define and promote a new standardized alternative to sample conditioning systems for analyzers and sensors • Standard fluidic interface for modular surface-mount components • Standard wiring and communications interfaces • Standard platform formicro analytics
What does NeSSI™ Provide • Simple “Lego-like” assembly • Easy to re-configure • No special tools or skills required • Standardized flow components • “Mix-and-match” compatibility between vendors • Growing list of components • Standardized electrical and communication (Gen II) • “Plug-and-play” integration of multiple devices • Simplified interface for programmatic I/O and control • Advanced analytics (Gen III) • Micro-analyzers • Integrated analysis or “smart” systems
Where Does NeSSI™ Fit in the Lab • Instrument/Sensor Interfaces • Design standards make development simpler • Reduced toolset to be mastered • Reduced sample variability to account for • Calibration/validation built-in • Consistent physical environment for measurement • Stream switching and/or mixing allow generation of standards to match analytical requirements • Reaction monitoring • Microreactors and continuous flow reactors • Batch reactors (with fast loop) • Sample Preparation • Gas handling (mixing, generation, delivery) • Liquid handling (mixing, dilution, conditioning, etc.)
The NeSSI Could Become the Base for a Micro-Analytical Lab‘A DEVELOPMENT PLATFORM’
