Instrumentation virtual electrochemical analyzer

An earher chapter discussed the electrochemical measurements with the aid of commercial and virtual electrochemical analyzers. Although the conventional electrochemical analyzers are capable of performing many different kinds of electrochemical analysis, the total cost and size of the commercial instruments limits their applicabUity in point-of-care diagnosis. Moreover, they also tend to be laboratory-based and not field portable. Therefore, the primary objective of this work is to develop a new, low-cost, hand-held electrochemical device for the measurement of the release of various biomarkers. 

Figure 5.24 Comparison of the electrochemical response of the SODI-CNT-PPy-Pt electrode measured using virtual electrochemical NO analyzer (curves a and c) and the standard physical instrument CHI 1200B (curves b and d) in the absence (curves a and b) and presence (curves c and d) of 500 pM NO solution in 0.1 M PBS (pH 7.0) at scan rate of 100 mV s versus Ag/AgCI.

Figure 5.25(a). Further, Figure 5.25(b)—(d) show the block diagram of the virtual electrochemical NO analyzer, front panel with block diagram of the potential sweep, and front panel with block diagram of the process of the virtual electrochemical NO analyzer. The overall electroanalytical performance of the virtual electrochemical NO analyzer was compared with the standard cyclic voltammetry instrument as shown in Table 5.1.
