Development of a micro electrochemical cell for in-situ deposition of 63Ni for use in electron capture detector (ECD) in gas chromatography

Abstract

Abstract In this work, we describe a novel electrochemical approach to deposit 63Ni coatings on the inner surface of a copper annular ring for its application as an ionization source in electron capture detector of gas chromatograph. A description of the electrolytic cell, the process of deposition and the experimental set up used, analysis of the nickel deposit and results are presented in this article. Sources containing ∼370 MBq (∼10 mCi) 63Ni could be prepared. The quality of the prepared source in terms of nonleachability, uniform distribution of activity and stability that are necessary before application were evaluated and found to be highly satisfactory.
