  1. Brian Marquardt and Dave Veltkamp Applied Physics Laboratory Center for Process Analytical Chemistry University of Washington Seattle, WA 98105 Combining Analytical Sensors and NeSSI to Improve PAT

  2. 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

  3. 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

  4. 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.)

  5. The NeSSI Could Become the Base for a Micro-Analytical Lab‘A DEVELOPMENT PLATFORM’

  6. NeSSI with an Array of Micro-Analytical Techniques will Impact Many Industries • Process Control • Process Optimization • Product Development
