1. Introduction and Background
NeSSI* & Micro-Analytics Workshop (* New Sampling/Sensor Initiative)
Introduction and Background
“the best way to predict the future is to create it”
2003 Spring Sponsor Meeting
Center for Process Analytical Chemistry

2. Our Process Analytics Legacy
Same Sampling System Design Practice for 20+ years
Discrete components & Basically Dumb
Lack of standardization
Result: Recognized as Weakest Link in Analyzer System
Typically Battleship Designs for Analyzers
Not real-estate friendly Ambient and environmentally challenged (read “ require A/C shelters”)
Poor Connectivity
Requires brute force methods for analyzer system integration (including critical interface to the process Control System)

3.  Hierarchical/Domain Connectivity Model for Process Analyzer System
Level 3 LAN
Enterprise Domain
Level 4 Enterprise LAN L4
Safety
Control/ Optimization
Environmental L3
DCS Domain
O&M Domain

AnLAN L2
Primary Data Path > Requires Maximum Integrity/Reliability
Level 2 LAN = Field LAN
Secondary Data Path > Requires High Integrity/Reliability
Measurement Domain 

7. Legacy Left us with the following Impressions ......
complex
expensive
proprietary
“big box”
outdoor operation
hi maintenance
industry: slow to change
Edvard Munch “The Scream”
And hurting us in the following areas
Cost to Build
Cost to Own/Operate
Reliability

8. The Drivers for Process Analytical Change
Reduce Cost to Build
Design and Engineering
Manufacturing and Installation
Reduce Cost of Ownership
Design Standardization
Simpler, less expensive maintenance
Enhance Reliability (Measurement Data Fit for Purpose)
Validate sample, data, communication

9. NeSSI Initiative
An ad hoc global industry initiative, formed in June, to drive permanent change in Sampling and Sensor Design and Implementation
Composed of End Users, Manufacturing Companies, Integrators
NeSSI mail-out has now grown to 350+ subscribers
Sponsored by the Center for Process Analytical Chemistry (CPAC) - legal umbrella
End User driven

10. NeSSI Objectives
Facilitate the acceptance/implementation of modular, miniature & smart sampling system and sensor platform (Adopt/adapt surface mount technology from SEMI)
Promote the concept of at the pipe/field-mounted (“byline”) analytical systems
Lay the groundwork for an open connectivity communication architecture down to lowest level of sampling system sensors/actuators (integrate NeSSI with ConnI)
Promote NeSSI as the macro-to-micro sampling platform for the emerging generation of micro-analyzers (e.g. “sensor/lab-on-a-chip” microanalytical devices)

12. NeSSI an Enabling Technology/Platform
What you will learn today:
NeSSI has evolved as a Sampling & Connectivity Platform
Sampling Interface based on an ANSI/ISA 76 Standard
Connectivity Interface
Standard Sensor bus (DeviceNet)
Standard Ethernet Interface for system integration
Primary Benefit: Platform enables accelerated development /commercialization of the new generation mini/micro analytical sensors/system (emphasis can be on analytical sensor)
3 Generations of NeSSI envisioned to fully exploit NeSSI capabilities
Analytical Application Clusters (enabler for sensor arrays)

13. NeSSI History
Concept of Modular Sampling System based on SEMI design conceived at ISA AD Meeting in 1998
Groundwork for NeSSI started at Nov 99 CPAC meeting
Initiative initiated in June 2000 (Issued RFP)
NeSSI promoted mainly at ISA and IFPAC meetings
Chronology of events trail at NeSSI Website

14. Workshop Goals:
Provide an overview of the technology trends and hurdles in the commercialization of the new generation mini and micro-analytical analyzers and sensors (MAS)
Validate and promote NeSSI as a MAS enabling platform with respect to both standardized sampling and connectivity interfaces
Explore and propose an enabling organizational mechanism such as an Analytics Interest Group, Forum etc. which would promote and facilitate the development, testing and deployment (commercialization) of the next generation of MAS systems
