On a separate occasion, a single 427.73 mg oral dose of the same antibiotic was administered to the same patient and the plasma drug concentration was determined as 0, 5.01, 5.77, 3.43, 1.1 mg/L at 0, 3.15, 7.69, 14.39, and 27.5 hours following the drug administration. Please calculate the bioavailability of this drug without utilizing any data fitting program.In Experiment 7, Isolation of Citrus Oils, the compounds isolated were the monoterpene compounds alpha-pinene, beta-pinene, limonene, myrcene and gamma-terpinene. The citrus oils were analyzed using gas chromatography, which separates compounds based on polarity and boiling point. Column chromatography and thin layer chromatography work on similar separation principles as gas chromatography, but rely only on polarity of compounds and solvents for separation. Explain why neither column chromatography nor thin layer chromatography would be appropriate separation methods for the terpenes isolated in Experiment 7. Answer:
