The meaning of MASS SPECTROMETRY is an instrumental method for identifying the chemical constitution of a substance by means of the separation of gaseous ions according to their differing mass and charge —called also mass spectroscopy.

Tandem mass spectrometry (MS/MS) is the leading technique for high-throughput elucidation of molecular structures. However, decoding a molecular structure from its mass spectrum is exceptionally challenging, even when performed by human experts. As a result, the vast majority of acquired MS/MS ...
The mass spectra of two series of alkane- and substituted-methanephosphonyl dichlorides have been studied together with the spectrum of benzenephosphonyl dichloride. The molecular ions are of low abundance. Ions corresponding to hydrocarbon or halomethyl groups, which occur by cleavage of the PC ...
摘要: The effect of oxidative-reductive pretreatment of ReAlO catalysts on their activity in methane aromatization has been established. Paramagnetic centers have been identified and their contribution to the conversion of methane into benzene over these catalyst is discussed....

Thus, control of the energy of the ionizing electrons can ensure the formation of a certain type of ion in the ionization chamber. It has been found experimentally that, at electron energies greater than 50 eV, the mass spectrum depends little on this energy. It has become accepted to charac...
