Web28 de ene. de 2024 · The m/z = 29 peak is produced by the ethyl ion - which once again could be formed by splitting the molecular ion either side of the CO group. Peak Heights and Stability The more stable an ion is, the more likely it is to form. The more of a particular sort of ion that's formed, the higher its peak height will be. WebTherefore, when an ion such as m/z 91, which is well represented in toluene and the other alkylbenzenes, is extracted, the result is a chromatogram emphasizing those particular components, and not showing any compounds that do not have m/z 91 in their spectra.
