Atomic methods are among the most sensitive of all analysis methods to matrix effects. The previous sections have described ways of trying to account for the possibility of some types of matrix effects. Even with these methods, there is still the possibility that some aspect of the matrix either enhances or decreases the signal measured at the detector.

This technique facilitates quantitative analysis by relating a cell???s potential to the concentration of electroactive species using the Nernst equation. It also covers different types of electrodes used in potentiometry, such as ion-selective electrodes, the significance of reference electrodes, and the impact of junction potentials.
