New Platform for Sampling and Sensor Initiative NeSSI

Micro Instrumentation for High Throughput Experimentation and Process Intensification - a Tool for PAT Edited by M. V. Koch, K. M. VandenBussche and R. W. Chrisman Copyright 2007 WILEY-VCH Verlag GmbH Co. KGaA, Weinheim ISBN 978-3-527-31425-6 

The development of NeSSI is very much a collaborative result of end-users, manufacturers, researchers, and many others working together to modularize and miniaturize process analyzer sample systems. The technical and standardization concepts of NeSSI have been well documented through numerous presentations and workshops throughout the last four years, including yearly updates at ISA, PITTCON and FACSS conferences and updates at the biannual CPAC meetings. 

Connecting the modular surface-mount components (and optional auxiliary components) in Fig. 10.1 is the NeSSI -bus, which provides the electrical power and communication functions for controlling actuators and transmitting 

Field-mounted analytical systems located in mini enclosures (boxes) near the point-of use for the analytical result (i.e., on-the-pipe monitoring). This implies a move away from expensive centralized analyzer sheds with their associated long runs of sample lines. 

Easy integration of sample systems with multiple physical/chemical sensors utilizing modem multi-drop commimication networks. An important aspect of the communication network (NeSSI -bus) is plug-n-play (i.e., self-identification/self-configuration of sensors and actuators) interchangeability. Increased use of small, smart, integrated sampling, sensor, and analyzer transmitters to provide more information about the sample and the process. Validation of representative sample and analysis.

The New Sampling an Sensor Initiative (NeSSI) platform for demonstrating and deployment of micro-analytical devices... 

It is envisioned that many of these technologies will ultimately be compatible with the NeSSI (New Sampling and Sensor Initiative) platform and, thus, will be added to the growing toolbox of characterization technologies that could be used in an array format for the generahon of meaningful data. The technologies described include ...
