Abstract: Abstract: The gas chromatography experiment presented here is a combination of a quantitative analysis of fatty
acids in edible oil with an analysis of a synthetic mixture to evaluate chromatography efficiency. This experiment
can be done in 5–7 hours. The students start with the preparation of the oil samples and standard solutions of
fatty acids. While the derivatization of the fatty acids is in progress, a synthetic sample is analyzed at different
linear velocity of the carrier gas. The students use the chromatograms to determine the Van Deemter equation
and to calculate the chromatography efficiency. The quantitative analysis of the oil samples can be done
consecutively or the samples can be stored until the next laboratory session. This combination of two gas
chromatography experiments is very attractive for the students because it deals with a real-world sample. In
addition, the students acquire practical experience in the significance of parameters related to chromatography
