An article by Dr. John Edwards of Process NMR Associates and researchers at the Southern Regional Research Center of the US Department of Agriculture (Dr. H.N. Cheng, Lynda H. Wartelle, K. Thomas Klasson) has been accepted for publication in the Elsevier Journal Carbon. The paper entitled “Solid state NMR and ESR studies of activated carbons produced from pecan shells” is available at the following link: Carbon Paper . Process NMR Associates provided the solid-state 13C NMR, TD-NMR, and ESR spectroscopy for the analysis of the activated carbons derived from pecan shells.

John Edwards and Paul Giammatteo of Process NMR Associates have written a chapter “Process NMR Spectroscopy: Technology and On-Line Applications” to appear in the 2nd Edition of “Process Analytical Technology” published by Wiley and Sons and Edited by Katherine Bakeev. The book will be published in May 2010 and is available for pre-order.
60 MHz TD-NMR System
Sep 13
Process NMR Associates and Spin Resonance Ltd have recently completed the construction a small 60 MHz (1.4T) 5mm TD-NMR system that can be utilized to study T1 and T2 characteristics of novel contrast agents at typical MRI frequencies. Here are a few pictures of the magnet. It is based on N42 neodymium-iron discs (120mm diameter x 30 mm deep).
Press Release – NMR Process Systems – Swagelok Technology Conference, Teaneck NJ - October 23, 2007
NMR Process Systems, LLC Announces : NPS-IS© – NPS Integrated Solutions
NMR Process Systems (NPS) announces a new era in advanced analyzer and process control solutions for on-line and at-line process applications. NPS’s Integrated Solutions (NPS-IS©) approach is designed to take advanced on-line analysis to the next level in delivering real engineering and economic benefit to the user.
NPS-IS©: the first and original source for any and all on-line NMR applications regardless of NMR vendor.
NPS-IS©: the first to offer integrated advanced analytical solutions using multiple technologies in one box.
NPS-IS©: the first to offer a fully integrated Swagelok sampling solution for improved sample switching and reliable measurement.
Too many spectroscopic based on-line analyzer projects (FTIR, NIR, NMR) have failed to meet expectations and/or objectives due to:
·Overselling the measurement
·Underestimating the sampling requirements
·Trying to replace all traditional analyzers with one technique.
NMR Process Systems is positioned to deliver the real benefits of advanced analytical systems in petroleum, petrochemical, chemical, food and beverage and pharmaceutical applications. Moving beyond the traditional replacement analyzer philosophy, NPS-IS© integrating analyzers and advanced controls to deliver real process improvement and economic benefit. Such integration leverages the strength of any individual spectroscopy, shortens per stream analysis time, and builds in internal cross-checking to ensure accuracy.

Abstract: The 21st century is envisioned to become the age of biology as renewable biomass resources replace petroleum in energy and industrial product applications. Motivated by concerns over national energy security, global CO2 reduction, a need for biodegradable products, and enhanced rural economic development, the engineering and construction of biorefineries for the manufacture of fuels, chemicals, polymeric materials and power from renewable resources is now a critical national priority. The context and intent of a biorefinery must be much more than simply replacing crude oil with renewable raw materials. A successful biorefinery must: 1) efficiently separate its raw material source into individual components, and, 2) be able to convert these components into marketplace products. The biorefinery must mirror the efficiency of today’s modern petrochemical refinery in using all components of its raw material source for the production of chemicals, fuels, and power.
Woody lignocellulosic biomass is a complex, composite material consisting of three polymers in close association: hemicellulose, cellulose, and lignin plus small amounts of low molecular weight extractives and inorganics. In this presentation, a group of synergistic biomass feedstock and biorefining technologies under development at SUNY-ESF, in collaboration with many industrial and academic partners, will be discussed including: short-rotation fast growing willow production, biodelignification, hemicellulose extraction, polymer conversion to fermentable sugars, biodegradable thermoplastics and hemicellulose-based composites.

Bio: Dr. Arthur J. Stipanovic is currently Professor and Chair of the Department of Chemistry at the SUNY College of Environmental Science and Forestry (SUNY-ESF) in Syracuse , NY , and also serves as Director, Analytical and Technical Services. His research interests include biodegradable polymers from renewable resources, high-throughput analytical techniques for determining the composition of woody biomass and new processes for the wood-based biorefinery. Dr. Stipanovic received both his B.S. and Ph.D. degrees from SUNY-ESF in polymer chemistry and much of his career was spent at the Texaco R&D labs in Beacon, NY, in new technology and lubricants research. He is a past Councilor and Executive Board member of the Mid-Hudson ACS section and, more recently, has served as Chair of the Syracuse section.
