A Brief History of Pine: Some Frequently Asked Questions Dr. Frank Dalton Pine Research Instrumentation Raleigh, North Carolina www.pineinst.com/echem
Our factory is located in Grove City PA Electrochemical Sales and R&D Office is in Raleigh NC Where is Pine located?
Question #3 Are you guys Electrochemists? Dr. Frank DaltonDr. Li Sun
Question #4 How did such a rural manufacturing company get into electrochemistry? Answer Historical Accident
Benjamin Levich It Began in Russia… Dr. Benjamin Levich pioneered the field of Hydrodynamic Electrochemistry in the 1950’s. He wrote a book called Physicochemical Hydrodynamics which was translated into English in 1964.
The book made its way from Moscow to Minnesota… University of Minnesota Benjamin Levich
During that same time period, Dr. John Albery from Oxford spent a summer in Minnesota… University of Minnesota Oxford University
Meeting of Minds in Minnesota Working in Dr. Bruckenstein’s lab were Dr. John Albery and two graduate students, Dennis Johnson & Duane Napp. During that time, they built Rotating Disk Electrodes and Rotating Ring-Disk Electrodes. Dr. Albery returned to Oxford and started a strong tradition of hydrodynamic voltammetry at that institution. (continued now by Dr. Richard Compton at Oxford). Dennis and Duane befriended an entrepreneurial under- graduate electrical engineering student named Ted Hines.
Nobody Stays Still for Very Long Ted Hines founded Pine Instrument Company
Rotating Disk Electrode & Rotating Ring-Disk Electrodes http://compton.chem.ox.ac.uk/john/Thesis/1-figs/rde.gif
Question #5 Do people still use the Rotating Disk Electrode? Answer Yes (amazingly) Electrochemical Methods: Fundamentals & Applications, AJ Bard & LR Faulkner, Wiley & Sons, New York, 1980
Question #7 How do you make the patterned electrodes? Answer The Same Way you Make T-Shirts
Mass Produced Electrodes The same technology used to make college T-shirts is also used to make electrochemical biosensors. Screen Printing is used to produce billions of disposable biosensor electrodes per year
