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.

Explain how gas chromatography differs from liquid chromatography.

What types of analytes can be analyzed using gas chromatography? What types of analytes are unsuitable for analysis with this technique? Which would be expected to elute first on a polydimethyl sioxane column, butane, or butanol? Why? What factors determine relative retention time with gas chromatography? What is the basis for separation in gas chromatography? (I.e. adsorption, partition, size exclusion, ion exchange, or affinity?)
