While the number of protons remains the same for all isotopes, otherwise the atom would change elements to one with a matching number of protons, the neutrons in the nucleus can change without changing the element. However, changing numbers of neutrons will result in isotopes of differing masses...

In an ocean that is rapidly warming and losing oxygen, accurate forecasting of species’ responses must consider how this environmental change affects fundamental aspects of their physiology. Here, we develop an absolute metabolic index (ΦA) that quanti
The molar mass of the starting metal (x), which is oxidized by oxygen (molar mass of 16 g/mol), can be calculated by Eq. (3.1): (3.1)xgmol100%=16gmoly% where x (g/mol) is the molar mass of the starting metal, 100% is the weight of the starting metal, 16 (g/mol) is ...
For example, the oxygen attachment dissociation method can generate lipid double bond position-specific fragmented ions, which are suitable for analyzing the double bond position of lipids (65). In the electron impact excitation of ions from organics (EIEIO) method, the resulting MS/MS is more ...

1A, we observe a mass difference of 0.5 Th between the isotopic peaks, which determines the charge number of the ion: z = 1/0.5 = 2. Similarly, for the ion in Fig. 1B, the observed mass difference of 0.33 Th establishes its charge number: z = 1/0.33 = 3. Computer algorithms can...
