Transcribed Image Text:On the next page is an LC separation of the parabens found in baby wash. Parabens are
suspected in a link to breast cancer therefore an accurate way to quantitate them is desired.
a. In the chromatogram, estimate k' for ethyl paraben. Clearly indicate what values you used for
all the terms in your calculation.
b. Is this a "good" value for a capacity factor? Explain.
c. What is the resolution between n-Propyl paraben and n-Butyl paraben? Again, indicate clearly
