GC-FID split peak issue

[swetha.rajagopal]

This is my first time using a GC-FID and i am trying to understand the difference between a good and bad peak. I ran an unknown sample on a DB-5 column at a program ramp condition set at 50c for 1 min, followed by 20c/min to 200c and hold for 2 minutes. I obtained peaks that were split and had retention times that were not similar to the ones I obtained for my reference samples (the unknown consists of any or a mixture of the 10 reference samples). How can I troubleshoot this problem?

You'll probably get more help if you post this in the Gas Chromatography forum with more information.
