Hi

 

I am new to GC Method development phase. We are having GC 7820 A with FID detector. Currently I am developing a method for industrial solvents. When I run a blank (THF), I got a very unusual spikes in the chromatogram as seen below. I have changed the inlet, septum and checked the gold seal which looks good and trimmed the column in the inlet end. Any suggestion would be of great help

 

Thanks
