elect all statements below that apply to Column Chromatography. Column chromatography can be used to purify small (< 0.1 g) sample mixtures. The compound in a mixture with the lowest Rf value will exit the column first. Column chromatography is often used to purify large (10 g) sample mixtures. Column chromatography is used mainly as an analytical tool.

Explain how liquids can be analyzed by gas chromatography. Briefly define or describe the function, in gas chromatography, of the carrier gas: stationary liquid phase: solid support: If ethyl acetate and n-butyl acetate are analyzed by gas chromatography, which of these esters will generally produce a peak with the shorter retention time? What operating variables determine retention time? Explain why is it important to inject the sample quickly.
