270=74 (m/z) +196 (Neutral molecule)
Discussions about GC-MS, LC-MS, LC-FTIR, and other "coupled" analytical techniques.

I was developing a neutral loss method for Methyl palmitate (270). In scan mode ,I got prominent EI+ peak at 74 (Mclaffarty rearrangement), there should be a loss of 196 {CH3(CH2)10CH=CH2}. When I put Neutral loss value as 196 and look for 270 peaks. I do not see it at all. why is that? Can someone with GCMS background help
