| Sep 30, 2016 at 13:57 | comment | added | KingBoomie | Thankyou for your effort! Can you please answer the questions beneath my update. If I get those two questions clear I think I'm done and can mark your answer. (answer them in your answer please) @alec_djinn | |

To explain a difference of 0.5 units in an m/z chart, z must be 2! It's not the mass that is 0.5. | |
| Sep 30, 2016 at 13:11 | comment | added | alec_djinn | Here you see the spectra of a molecule having 2 positive charges, the zoom-in picture on the right shows how the peaks of that specific compound are 0.5 units distant from each other. | |
| Sep 30, 2016 at 12:58 | comment | added | KingBoomie | Do you have a spectrum example of this to clarify what you are suggesting? alec_djinn | |

| Sep 30, 2016 at 12:36 | comment | added | KingBoomie | That's exactly what I thought until I read the givin citation that isotopes can be used to determine the charge of ions in the spectrum @alec_djinn | |
