(A) Linear curve and the corresponding 95%-confidence interval describing the current density in dependency of nitrite, neglecting temperature and pH (Model B, Equation (4)). (B) Comparison of the residuals of the model best describing the correlation (Model A, Equation (3): including nitrite, temperature and pH) and the linear model only depending on nitrite (Model B). The results were obtained with the large sensor.
