Theoretical nernst slope
WebbThe confidence limits for the slope are then b±tn-2sb and for the y-intercept a±tn-2sa. For a large number of samples with a 99% confidence interval, we can use tn-2 = 2.58. For the fluorescence data, the standard deviation of the slope is sb = 0.0409, so the slope with confidence interval b = 1.93 ±(2.58 × 0.0409) = 1.93 ±0.11. WebbStandard ROSS electrodes provide the same rapid response, accuracy and temperature response of all ROSS electrodes.
