2nd GENERATION IGC TECHNOLOGY
3
SYSTEM CONFIGURATOR SOFTWARE

• EASIER TO DESIGN

• EASIER TO ASSEMBLE

4
TRADITIONAL VS. MINIATURE MODULAR

• MEASUREMENT OF PPM H2O AND O2 IN A HIGH PURITY
  HYDROCARBON STREAM - MINIATURIZED

5
A REAL SYSTEM
6
TRANSFER CONSIDERATIONS

• SEMICONDUCTOR
• Quantifiable volume of ultrapure gas to point of
  use.
• Few functional components
• Metal interface seal
• Basic control requirements

• SAMPLE SYSTEMS
• Minimal properly conditioned sample to an
  analyzer
• Large variety of functional components
• Elastomeric interface seal
• Complex control requirements

7
CONVERSION REQUIREMENBTS

• Change the substrate
• Modify the flow components
• Add additional down mount functional components

8
PRELIMINARY SERVICE TEST RESULTS

• Easy to design, assemble, install, operate, and
  monitor
• Leak-tight
• No evidence of cross contamination of multiple
  streams
• Increased response time

9
NeSSI EVOLUTION

• GENERATION I
• Modular, established feasibility
• GENERATION II
• Smart, fully automated, intelligent control

10
GENERATION II CHARACTERISTICS

• CPAC GENERATION II SPECIFICATION
• Integrates electrical components into Generation
  I designs
• Addresses safety requirements for use in
  hazardous areas
• Both functional and conceptual

11
SMALL, SMART SAMPLE SENSOR SYSTEMS

• Provide plug-and-play hardware components and
  software which
• Tracks reliability and Self-adjusts for optimal
  performance under variable conditions
• operations metrics
• Provides an intuitive self-diagnostic GUI

12
THE FUTURE

• Hardware development
• Full selection of down mount functional
  components
• Intelligent components
• Required sensors
• Intrinsically safe actuators
• Agreement on communication protocol
• Intrinsically safe protection solutions
