What is Gas Chromatography: Alcohol Analysis about?

This document describes a gas chromatography experiment to determine the percentage of ethanol in water-ethanol mixtures using n-propanol as an internal standard. Students will create standard solutions with varying concentrations of ethanol from 4-25% by volume and a constant concentration of n-propanol. They will analyze these standards and an unknown sample on a gas chromatograph. Students will calculate retention times, peak areas, and efficiency to identify the components and create calibration curves
