Low Energy Collision-Induced Dissociation of PPG & PEG Based Polyetheramines in ESI MS?

I have tried NaCl infusion during LC & found this does increase dissociation to some degree. I have read that LiCl & AgCl are also possibilities. Is there any other way to get even greater dissociation -- such as hardware that can be attached to my current UPLC SQD ESI system?

  • Hello

    Apologies that we missed this, until now. However, there is no easy answer. What you have suggested is possible, but a triple quad is probably best too for this. This is not something that an LC person should speculate about. My suggestion will be to put you in touch with a MS application specialist instead so please expect an email on this.
