Hi guys

I and my teammate used Gas Chromatography for the first time today in class to analyze the sample we made, but I'm having trouble reading the results. Can you guys help me?

The 1st graph is of 1-Butanol

The 2nd graph is of the 1-Bromobutane synthesized using that same 1-Butanol (with reflux and simple distillation)

The way I understand it, the 1st peak in the 2nd graph should be that of 1-Bromobutane and the 2nd peak should be that of traces of 1-Butanol. Is it correct? I'm a little bit unsure because the time in 2 graphs is different, 1st one is 3.723 and 2nd one is 3.110
