|Abstract:||When called upon to investigate the properties of a new chemical system, the electrochemist draws from a standard repertoire of techniques such as cyclic voltammetry and chronocoulometry, each having a particular investigatory power, i.e., cyclic voltammetry for reaction mechanisms and chronocoulometry for adsorption. After deciding which techniques to use, a substantial amount of time must be used to prepare and execute each experiment, and to organize and to refine the resulting data. Analysis of the data usually requires an electrochemist's years of knowledge and expertise, a rare and costly commodity. This thesis investigates one approach to automate and thus lower the cost and widen the distribution of analysis by electrochemical methods.
The automating system involves a microcomputerized potentiostat, distributed commercially as the Bioanalytical Systems BAS-100, which is remotely controlled by a VAX minicomputer via a serial data link. The VAX executes a set of 142 modules, which together form a fairly general instrument controller package called CYBER(,--)II. Written entirely in FORTRAN-77, CYBER(,--)II allows one to form a tree data structure defining an experiment executable on the BAS-100. With a minimum of overhead, an electrochemist can construct a CYBER(,--)II a study, e.g., for product stability, and later have that study automatically performed on the BAS-100, either for his own or another researcher's use.
The design, organization, and execution of CYBER(,--)II are presented in this thesis, as are examples of its product stability analysis of both cadmium and anthraquinone disulphonic acid systems.
