what is the definition of limit of stray light in UV calibration

Answer Posted / bhupalreddy

Stray light is defined as the detected light of any
wavelength that is outside the bandwidth of the selected
wavelength, Stray light causes a decrease in absorbance and
reduces the linearity range of the instrument. High
absorbance measurements are more severely impacted by stray
light....

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
