Gas Chromatography: Purifying alcohol

Introduction
The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied substances) but can determine their concentration. Finding out what is present gives us a qualitative analysis and finding out how much of the analyte is in the mixture gives us the quantitative analysis. The following picture shows the structure of a chromatographer.©ö





The gas or in our case a liquid is injected through the port turned into a vapor through the nebalizer. The vapor then proceeds through the column. The mobile phase is the gas and the column is the......
