Question

B. What amount of stray light produces an apparent absorbance of 1.995 with a true transmittance of 0.0100? Incorrect. See the lower panel for more information on how to determine the amount of stray light Number S-.0889 In the process of performing an analysis, you determine that you need to improve the precision by limiting ne error in the absorbance to 0.00006100. You attempt to achieve this by reducing the amount of stray light that reaches the detector. What is the maximum amount of stray light that can reach the detector that will limit the error in the absorbance to 0.00006100 for a true absorbance of 1.5000000?

Explanation / Answer

measured absorbance = -log(T + r)

T+ r = 10^(-1.995) = 0.010116

T = 0.1

So, r = 0.000116

= 0.0116 %

A 10^(-A) True Absorbance -> 1.5 0.031622777 True + Error -> 1.500061 0.031618335 Difference = 4.44135E-06 0.000444135 %
