Question

What stray light % will give an apparent absorbance of 1.998 with a true transmittance of 0.010? In the process of performing an analysis, you determine that you need to improve the precision by limiting the 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 1.6000000.

Explanation / Answer

Hello

Question B.

Apparent Absorbance = True Absorbance x Stray Light

Stray Light = Apparent Absorbance/True Absorbance

True absorbance = -log T

True Absorbance = -log0.010 = 2

Stray Light = 1.998/2 = 0.999 = 1 %
