Absorbance of the sample solution is 0.152AU. The three main uncertainty sources of absorbance in photometric analysis are repeatability, drift of the photometer and uncertainty due to possible interfering effects. The respective uncertainty components were estimated by the analyst as follows: Repeatability standard deviation is 0.005AU, uncertainty due to possible drift is ± 0.001AU and uncertainty due to the possible interfering effects is ± 2% of the absorbance value.
Please calculate the combined standard uncertainty of absorbance. Please provide 4 decimal places after the decimal point.
