(a)

Interpretation Introduction

Interpretation:

The appearance of the upper chromatograms and what would the chromatogram of pure (R)-gimatecan look like on the same two stationary phases has to be explained.

(b)

Interpretation Introduction

Interpretation:

The appearance of the two lower chromatograms and why it can be concluded that the gimatecan contained 0.03% of (R)-enantiomer and why it is not observed on the (R,R)-stationary phase has to be explained.

(c)

Interpretation Introduction

Interpretation:

The relative retention for the given two enantiomers on the (S,S)-stationaryphase has to be found.

(d)

Interpretation Introduction

Interpretation:

What would be the resolution between the two peaks in a racemic mixture of (R), and (S)-gimatecan has to be explained, if the peaks were symmetric the given baseline separation signal returns to baseline before the next peak begins has to be explained.
