Homework Help: Chemistry

Posted by mandy on Saturday, February 18, 2012 at 8:11pm.

I conducted a Gas Chromatography experiment using Flame Ionisation Detector (FID).A capillary column was used.
1)Blank
2) Standard
3) Sample
4)Blank
5)Standard
The above was injected into the system.

In 2)Standard chromatogram,a sharp, thin peak was observed between the 2 principal peaks. This peak had area count of less than 100.
This sharp peak was also seen in 4)Blank.

However, this sharp peak was not present in 5)Standard chromatogram.
Can you suggest a reason for this sharp spike/peak seen in 2) and 4)?
