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

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 for micro 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.)

8 NeSSI™: Enabler for MicroAnalytical
Standard “connectivity” (the “rail” concept) Standard Electrical (Digital) Interface “Rail” SAM* P V Standard “hockey-puckPC” Anyone’s Sensor Anyone’s Actuator It is really about creating a set of standard interfaces, so current and new analytical devices and sample system components can be quickly and easily integrated into the process environment. A standard electrical interface that will provide power, a standard communication format, and standard protocol between these devices. A standard software package that will allow for inter device communication, control, and diagnostics at the installation level. And a standardized portal and protocol for communication with the plant DCS or Enterprise Management System. A standard mechanical interface. A standardized footprint for interfacing these devices and components with the process sample. Standard Mechanical Interface “Rail” *Sensor/Actuator Manager What technologies are available Suitability for modular sampling systems

12 ABB Natural Gas Chromatograph
Dimensions: 6.75“ dia. × 16'' long × 9.00'' tall Weight: Approximately 28 lb. (12.7 Kg) Analysis section contains stream selection solenoids, pressure regulation, 32 bit digital detector electronics and a dual-train chromatograph in a single, replaceable module (coffee-cup sized)

13 Siemens microSAM GC Valveless live injection with software-adjustable injection volume Maintenance-free column switching and electronic pressure control Accurate measuring results by multiple parallel micro-detectors Can be mounted directly at the sample extraction point because only a single auxiliary gas and very little electrical power is required Simple remote control with Windows-based software and Ethernet communication i.e. MicroSAM uses a thermal conductivity detector array integrated on silicon to measure all column and vent flows as well as the injection peak itself

14 Agilent 3000 Micro GC Dimensions: 5.9” x 9.8” x 16.1” Wt: 18 – 37 lbs (portable) Custom configurations with 1 to 4 replaceable chromatographic channels. Choose from various micro-machined injectors, columns, sample conditioners, and application-specific reports. The modular GC design maximizes uptime, with repair as simple as exchanging one module for another. Increase sensitivity, maintain high precision, remove unwanted contaminants from your sample, or speed up analysis with variable, fixed or backflush injection options. Digital pneumatics control carrier gas flow electronically, enhancing reliability and precision while further simplifying operation.
