Is the breakthrough in smart sampling technology at hand? An update of progress & missing links on the road to Ne. SSI Gen II Rob Dubois CPAC Workshop, Seattle, WA, May 11, 2006 “the best way to predict the future is to create it”

Presentation Outline • • • The Roadmap and Generations Progress and missing links Example of an enabler How do get the WOW factor Summary and questions 2

Ne. SSI™ Roadmap 2008 -2012 2004 -08 Gen III u. Analytical END USER VALUE Gen II Electrical Networked & Smart Gen I 2000 -04 Fluid Components 3

Progress on 7 elements of Gen II • • (1) Smart transducers (2) Programmable heated substrate base (3) Combi valve (4) Multi-Drop IS serial bus (5) temp. controlled micro. Climate enclosure (6) Sensor Actuator Manager (SAM) (7) PDA – graphical user interface 5

(1) Progress: Transducers • Flow – Thermal – cons: current load, wiring complexity, robustness? – DP with orifice – cons: pressure drop, size, cost? – Rotameter switch/tx cons: cost and size – need new technologies • Pressure & Temperature • Analytical (early stages) • Objective: – single block, multi-drop – combine transmit and local indication into one package Courtesy of FCI 6

(2) Progress - Smart Heaters • Approved for ATEX/CSA Zone 1 • First identified in 2003 now deployed in several locations • Missing link is the connectivity to smart devices or stand-alone Courtesy of Intertec 10

Smart Heaters – the value • Increase Reliability – early detection of heater failure (prevent freezing and condensation/2 -phase systems) – networking allows remote monitoring and setpoint change • Technology Enabler – precision temp. controls supports the use of microanalytical on a substrate – enables ramping and zoning – in combination with a precise flow meter allows use of permeation calibration devices eliminating gas cylinders • Enhanced Capabilities – higher temperature operation by controlling heater surface below the T-zone temp. - an alternative to air bath systems • Cost Savings – conduction heat is more efficient than air heating – allows smaller package by compact hotplate design 11

(3) Combi-Valve Proposed • Modulating & On. Off Valves – challenges • • • size power budget cost networking technology to make modulating is tough A Comm. Vent D/A Solenoid Inst Air Actuator Valve – Proportional Valve is missing link 13

Simple On-Off Valve Driver • Current solution – on/off solenoid manifolds – needs “safe” area for installation – various buses Courtesy of SMC 14

(4) Progress: Multi-Drop Intrinsically Safe Bus • The inability to align to a standard has prevented us from moving ahead – component makers “in limbo” • Good Features: plug and play, IS, low cost, low power, small range, std. connector • Is this still the missing link? 15

(5) Enclosure Progress: Clamshell Design – Flexible Connections Still a need for convection heating…. Courtesy of Exxon. Mobil 16

(6/7) SAM and the PDA • Concentrates sensor/actuator signals – without this capability we will be doomed to dumb systems – running signals from each sensor & actuator to a facilities DCS system is not cost effective – handheld PDA useful for local monitoring & simple control 17

Enabler: Small flows allow wider use of catalytic sample disposal systems • cost savings enabled by byline analysis and low volume modular systems – eliminate vents • environmental protection – a temperature sensor can monitor catalyst depletion or heater failure and alarm that unit is failing • performance enhancement – atmospheric reference with no environmental impact – no analyzer backpressure issues TRACErase is Courtesy of Mer.

How do I achieve the WOW factor? • • Function Intensification Reduce weight and space Easily reconfigurable Simplify the design and spec process – one stop shopping, integration and check-out Plug and Play communication Minimize certification issues Sensor/Actuator signal concentration/control loops SMART (automated) – but configurable and easy (fun? ) to use for the analyzer technician (e. g. intuitive menu structure and graphics) 23
