Methods for Improving Precision in Absorbance Measurements

As shown here, the relative uncertainty in determining absorbance (and thus in determining concentration) is greater at very high and very low absorbances (that is, when very little or almost all of the source radiation reaches the detector. One way … Continue reading

Precision

Two determinations of the concentration of K+ in serum, showing the effect of precision on the distribution of individual results. The data in (a) are less scattered and, therefore, more precise than the data in (b).
