Web1 jul. 2016 · If you want to determine the mass of an ion, then the other answer is right and you can just multiply the m / z by z, the (absolute value of the) reduced electric charge. If you want the mass of the parent neutral molecule, you will (a) need more information, and (b) have to do a bit more work. WebResolution is not a number, it is a function. Thus it depend on the exact m/z value. Unfortunately there are lot of problems with the IUPAC recommendations (do not dare to call it definitions). Webm / z 29 could be either H C O + or C 2 H 5 +. The former could be a secondary fragmentation of m / z 31 after H 2 loss, whereas the latter could be produced as a heterolytic bond cleavage of the C-C bond. (In fact it is the same bond elongation leading to m / z 31, except that they electron remains on the opposite side.) thyme belfast menu

"WebIt has long been called the mass-to-charge ratio although m is not the ionic mass nor is z a multiple or the elementary (electronic) charge, e. The abbreviation m/e is, therefore, not recommended. Thus, for example, for the ion $\ce{C7H7^2+}$, m/z equals 45.5. Could someone please explain the definition?
