Dear Colleagues,

I am currently running positive ESI (LC/MS) on an LCQ unit. In a blank run,
a huge peak shows a mass spectrum with a bunch of peaks with mass
difference of 113 (340, 453, 566, 679, 792, 905, 1018, ...). Does anyone
have any idea what these might be? I assume those are clusters.

Your suggestions and comments are greatly appreciated.

Thank you.
