LCMS peaks were identified and quantified by comparison with a genistein standard (Sigma) for elution time, mass spectrum and Retro-Diels-Alder (RDA) fragment masses of collision energy fragmentations performed in the trap with helium.
This again supports JAXA's assessment that this was not a high-energy fragmentation.
In the following, only the basic applicability of the method to low-energy fragmentation events such as the one currently being analysed along with its potential accuracy and precision is assessed.
Binding energy per atom, second-order difference of cluster energies, fragmentation energy, dipole moment, Al Al bond distance, and chemical hardness of nanoclusters were calculated and discussed.
Alternatively, HILIC fractions may be analyzed by with MALDI-TOF /TOF -MS /MS) detection, which MALDI-TOF /TOF -MS /MSigh-energy fragMALDI-TOF /TOF -MS /MSdetection61, 162].
Characteristically, the native vitamin D compounds show very rich product ion spectra, due to the availability of a large number of low-energy fragmentation pathways.
One example, known as MSE, attempts to do so by rapidly alternating between a high- and a low-energy fragmentation, with the objective of producing a low-energy spectrum that contains few or no fragments so that the original metabolite can easily be identified, using its corresponding fragments observed in the high-energy spectrum.
Overall, according to the binding energies per atom, second-order difference of cluster energies, and fragmentation energies it can be concluded that Al7 is the most stable cluster among all Al n clusters studied here.
It has been conclusively shown that such machines yield significant quantitative energy-fragmentation information about industrial ores.
