Distillation of Essential Oil from Cloves
Example GCMS Data
(from Summer 2008 lab)

Everyone's results were very similar, so only one set of data is included here. Some questions you should consider and answer in your report:

1. How many components are in the clove oil mixture, according to the GC?
2. What is the percentage of each component in the mixture?
3. Which of the components corresponds to eugenol? Compare the MS data to literature data to support your answer.
4. Is eugenol the major component of the mixture?
