PLEASE HELP.

I'm using a Mass Spectrometer and I have a contaminant at 214 in every sample i run.

Im trying to figure out what this 214 is. Ive found one candidate, which is trinitrobenzene, but i doubt that this is being formed from the beta-lactams i am making.

Does anyone have an idea what weighs 214 as a molecule or as a molecule-adduct forming from the fragmentation of beta lactams?

I just need you guys to throw out candidates that would have a molar mass near 214.

PLEASE HELP. This is for science.
