ELECTROCHEMICAL SENSOR UTILISING A DUAL REDOX SYSTEM CONTAINED WITHIN A SINGLE MOLECULE |
摘要 |
An electrochemical sensor utilises a chemical compound which is not a macromolecule but rather is a single chemical compound of determinate structure, incorporating two redox systems which differ in their response to a species to be detected. In one form, one redox system displays a voltammetric wave which is pH dependent while another displays a voltammetric wave which is pH independent and acts as an internal reference. The sensor comprises a solid substrate, which may be carbonaceous, on which the compound is immobilized. The sensor may be incorporated into a tool to be suspended in a wellbore. |
