Hinshaw: Challenges of a Remote Online GC Monitoring System
John Hinshaw
BPL Global & ChromSource
Abstract:
Reliable long-term deployment of online GC monitoring systems in truly remote locations presents a number of challenges encountered neither in the laboratory nor in localized online process control or monitoring systems. An important example described here is the routine monitoring of fault gases in electrical insulating fluids; such monitoring helps to identify and track problems in electrical generation, transmission, and distribution transformers before potentially catastrophic failures occur. This presentation discusses a dedicated monitoring system that utilizes an online membrane extraction system and miniaturized gas chromatograph to quantify dissolved gas concentrations in live transformer oil every 1–4 hours, with a design maintenance interval—including the carrier gas and columns—of four years and an environmental rating that covers greater than 95% of available deployment locations worldwide. The monitoring system comprises three major components: a membrane gas extractor, a miniaturized gas chromatograph, and a microprocessor control subsystem, all contained in a small temperature-controlled environmental enclosure. The design engineering process and transfer to manufacturing yielded an improved high-sensitivity thermal conductivity detector, a proprietary porous polymer column packing, a unique multifunction rotary stream selector, and new data processing algorithms. The system has been in routine production since 2005.
About the Speaker:
John Hinshaw is Sr. Research Scientist at BPL Global–Serveron Corporation, where he has worked on the design and implementation of online analyzers for the Smart Electrical Grid since 2002. Previously, Dr. Hinshaw worked in gas chromatography instrument R&D for twenty years: at PerkinElmer for sixteen years, variously as Senior Staff Scientist, Worldwide GC Technology Manager, and GC Applications Manager, and before that at Varian. Dr. Hinshaw is well known for his contributions as the “GC Connections” and “GC Troubleshooting” editor at LC•GC Magazine since 1988. John has conducted a large number of one- to four-day professional courses in chromatography at national and international conferences, as well as numerous on-site courses at industrial locations. He has published over 140 scientific papers, books, and chapters, plus six patents. He is the chair of ASTM E13.19 on Separation Science, a member of ASTM D27 on Electrical Insulating Fluids, CIGRÉ, and IUPAC. He also is a member of the Editorial Advisory Boards of the Journal of Separation Science and LC•GC Magazine, an Associate Director of the California Separation Science Society (CASSS), and he serves on the Executive Committee of the Subdivision on Chromatography and Separations Chemistry of the ACS Division of Analytical Chemistry. For three years he served on the NSF WIMS ERC Advisory Review Board. John recently was appointed to the USP Council of Experts, Expert Committee on Analytical Chemistry, 2010-2015. Dr. Hinshaw received his Ph.D. in Analytical Chemistry from Duke University in 1979.
