Element Six and Warwick University announced the development of a new boron-doped CVD diamond electrode for use in extreme electrical analytical sensing applications.

At the Pittsburgh Analytical Chemistry and Spectroscopy Applications Conference & Exhibition (March 17-21, 2013), Element Six announced its DIAFILM EA, an electrochemical analytical grade diamond material designed in collaboration with Warwick University.

This monolithic self-supporting boron-doped diamond electrode synthesized by microwave CVD process is expected to revolutionize sensing technology and is expected to drive the development of next-generation extreme electrical analytical sensing technology for biomedical, environmental, food, and pharmaceutical applications. Benefits in areas such as oil and gas.

DIAFILM EA has excellent chemical inertness and stability to overcome long-term stability problems in extreme environments such as corrosion, high temperatures and high pressures. In many of the most demanding applications of electroanalysis, other electrode materials can only be used in a single use, while DIAFILM EA can run thousands of cycles. DIAFILM EA also delivers the highest levels of sensitivity, selectivity and responsiveness due to its high phase purity and optimized conductivity.

Element Six has been actively collaborating with business partners in enhancing electrochemical sensing applications with the newly launched DIAFILM EA material to demonstrate the superior performance of this next-generation sensing material. With the widest electrochemical potential window and lowest background current and capacitance of all electrode materials, DIAFILM EA is expected to revolutionize electrochemical sensing systems and technologies.

"In the past decade or so, due to the industry's need for electrode materials with high electrical conductivity and phase purity, boron-doped diamond film electrodes have not yet met the technical requirements," said Adrian Wilson, manager of Element Six Technologies Division. "We have produced a boron-doped CVD diamond with ideal conductivity and 100% phase purity to meet this market demand. Based on its unique properties, DIAFILM EA will drive the development of next-generation sensor systems."

“The research and development of synthetic diamond as an electrode material has demonstrated the potential to change sensing technology,” said Professor Julie McPherson of the University of Warwick. “Element 6 CVD diamond is an exciting material. We have been working together for 6 years and the two sides have been very happy."

The technical work of synthetic diamond was completed and developed by Element Six's R&D team in Aesco, UK. The electrochemical and interface group of the Department of Chemistry of Warwick University completed the electrochemical characterization test of DIAFILM EA materials.
