A$)$ Reconstruct the original chromatogram.

B$)$ Considering that the number of theoretical plates is $150$ and the flowrate is $0\mathrm{.}5$ mL$/$min$.$ Plot the

yield and purity as function of time if fractions are collected after $4\mathrm{.}4$ minutes.

C$)$ At what time you should stop collecting antibody if it is desired a purity $>98\%$
