compare your results with pure sample of each component. each compound exhibits a unique retention time.

Please also check the base line and the purity of the carrier gas.

Also run it through a GC-MS that'll give you more data.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
