Based on our TLC analysis, we can determine which fractions contain which purified compounds and combine those in our tared, labeled filter flasks.
It looks like fractions 4-6 contain only aspirin, 8-13 contain only acetaminophen, and 16-20 contain only caffeine, so we will pool those fractions in the corresponding filter flasks.
Note: We do not want to combine any mixed fractions with pure fractions!
