Hello
I receive my HRMS result and I think the results show I got the compounds.
But I always observe peaks with double or even triple the molecular weight of my stuff. I think this is dimer.
Anyone can elaborate the formation of this dimer or trimer???

This type of question is really meaningless without providing, at the very least....
1. The method of ionization (EI, CI, ESI etc)
2. The mode (+ve or -ve)
3. The molecular formula
4. The m/z values observed
