The GC chromatographic results report quantities of each component present in a sample in terms of area percent. It is then necessary to adjust the area percent because:
To reduce instrumental error during the sample run.
To ensure complete separation of the compounds.
So that they more closely match the standard retention times.
To exclude the quantity of the solvent.
Homework Answers
Area under the GC chromatography peak gives us the concentration of the compound. The area is adjusted during the GC chromatography run to ensure that the complete separation of the compound has taken place.

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
