# Question #df800

Because the peaks obtained from $\text{GCMS}$ trace are not triangles?
The peak observed on a $\text{GCMS}$ trace is not a triangle, but a Gaussian, whose integration requires more mathematics than I am comfortable with. Anyway, you have to trust your instruments. If it gives the area under the curve, unless there are compelling reasons to reject the data, the data are the ones you have to quote.
