Gas Chromatography with Samples of Three Different Compounds
Purpose:
The goal of the experiment is to get more familiar with gas chromatography to determine
ratios of acetone, methanol, and propanol in a standard sample and two unknown solutions A and
B. The overall goal was to determine percent composition through several calculations including
correction factors.
Procedure:
In the lab, a gas chromatograph was warmed up and preset for the desired temperature
program which was running at a set temperature for 2 minutes per run. A standard sample
consisting of a known composition of 2 grams acetone, 2 grams methanol, and 2 grams propanol.
Two unknown samples were also given and the goal was to determine the amount of acetone,
methanol, and propanol was in each unknown sample. There were two options for the unknown
samples, one option was to have 1 gram acetone, 2 grams methanol, and 3 grams propanol. The
other option was to have 3 grams acetone, 2 grams methanol, and 1 gram propanol. Each sample
(standard, unknown A, and unknown B) was ran 6 times and then had the average taken for each
area under the curve. These averages were then used to help calculate correction factors and
percent composition of the unknown samples.
Results and Discussion:
The following tables present the GC readings from samples of a standard and unknowns
A and B. The results that were obtained in lab were used to calculate a correction factor for each
