Who is John Harrison?
Like squaring the circle or inventing a perpetual motion machine, the phrase 'finding the longitude' became a sort of catchphrasefor the pursuits of fools and lunatics. Many people believed that theproblem simply could not be solved.

Today’s Analytical SystemThe Technology of Last Resort!
• More of an “art” than a “science”
• Expensive– up to 60% of costs
after purchase• Require large sample &
utility usage• Skilled maintenance staff
required

Technology Explosion!
• Fast networks/computers
• Robust/miniature electronics
• Lab-on-a-chip; optics; wireless
• Fiber optic sensors
What does the Market Need?
• Reliable, rugged, low cost & fast
What are the Critical Issues?
• Development Cost
• Technology hurdles
• Market acceptance

MicroAnalytical & Process Analytical

The Ideal microAnalytical Device for Process Analytical (1/4)
• Has global electrical (hazardous) Certifications• Embedded multi-drop digital protocol• Plug & Play (self-identifies)• Robust (> 99.9% uptime)
– Embedded smarts/Self-diagnostics– minimum or no moving parts – modular replacement
• Low cost (c. <$5K)– <$1K “disposable”
• Embedded documentation
rnd/May 6, 2004 6
The Ideal microAnalytical Device for Process Analytical (2/4)
• Multi-Component Analysis– multi-component: GC, MS, SPECTROSCOPY– unimolecular sensors
• Suitable for operating as a Functional Clusters– pH, DO2, Conductivity: “water package”– NOx, O2, CO: “CEMS package”
• Gas and/or Liquid Service• Wide Sensitivity: “Configurable” rangeability
– PPB, PPM, PERCENT
rnd/May 6, 2004 7
The Ideal microAnalytical Device (3/4)
• Fast (continuous) Response (< 10 seconds)• Physically small in size • Low Power (for intrinsic safe operation)• Impeccable selectivity
– under both normal & upset conditions• 316L SS (typ.) or process compatible• Self Correcting (drift compensation within limits)
– Ambient temp/pressure changes– Sample pressure/flow/temp changes
• Self-checking/calibrating• Low/No Utility or Reagent Usage
rnd/May 6, 2004 8
The Ideal microAnalytical Device (4/4)
(conditioned sample)• Typ. Pressure:
– (typical) vacuum to 150 psig– (higher) vacuum to 500 psig
• Typ. Temperature: -20 to 80 C.• Flow (gas)
– 3 to 200 cc/min and 3 to 2,000 cc/min• Flow (liquid)
– 1 to 300 cc/min and 1 to 1,500 cc/min

NeSSI™ an Enabling Technology for microAnalytical
• provides clear “standards”• lowers infrastructure development costs and
associated entry risk (faster to market)• developer can concentrate on providing a
premiere microAnalytical sensor – rather than infrastructure

Conclusion
• NeSSI™ provides an enabling platform for microAnalytical
• microAnalytical will provide the greatest value and impact to End Users
• Just like John Harrison, finding the longitude in microAnalytical, is fast becoming a reality. Solution to longitude
problem – a miniature, accurate, seaworthy timepiece.
