“…Comparing the detection and quantification limits obtained for benzocaine using BIA associated with amperometric detection, it was verified in the literature that the values are similar to others studies involving electrochemical techniques, applied to different samples . However, it was not possible to make this comparison for tricaine, since there are still no reports in the literature.…”

Determination of Benzocaine and Tricaine in Fish Fillets Using BIA with Amperometric Detection

A system based on batch injection analysis (BIA) associated with amperometric detection at screen‐printed carbon electrode was used for the precise and rapid quantification of the anesthetics compounds benzocaine and tricaine in fresh fish fillets. Along this study, the best conditions for the BIA‐amperometry system were stablished for the rapid determination of these compounds. The results obtained demonstrate that the proposed method is an interesting alternative to the chromatographic methods, once it allows to perform rapid analysis (more than 300 injections per hour) with low limits of detection (3.02×10−8 mol L−1 for benzocaine and 3.19×10−8 mol L−1 for tricaine), using just 80 μL of sample for each analysis. Furthermore, it was possible to obtain high repeatability for both compounds analyzed, demonstrating good performance. The simple sample preparation developed in this study drastically reduced the amount of fat in the fish extract, favoring precision, as shown by the results of the recovery studies of both anesthetics contained in the fish samples (values above 99 % for both analytes).

“…Amperometric sensors using carbon printed electrodes (CPEs) have many advantages such as being portable and disposable, as well as being able to be used successfully for the quantification of different compounds . In addition, CPEs can be easily coupled to batch injection analysis (BIA) for rapid analyses with high sensitivity .…”
