An object oriented approach to electroanalytical technique implementation

This work describes the application of object oriented software design to the development of a low cost, functionally versatile, PC-controlled potentiostat system. The implementation time for the electroanalytical techniques has been drastically reduced within the object oriented environment and it is shown how this approach simplifies the addition of new techniques without recourse to extensive software or hardware redesign. The pertinent aspects to the object oriented technique in the design of the potentiostat software are described in detail and experimental results are presented for chronoamperometry, cyclic voltammetry and square wave voltammetry for the one-electron transfer compound, potassium hexacyanoferrate(II) in aqueous solution. It is also shown how new electroanalytical techniques based on novel potential-time waveforms can be rapidly and easily incorporated, and experimental results for the highly sensitive pulsed amperometric detection of glucose in a stirred cell are presented.
