[1] [2] [3] The accelerating voltage V, and the magnetic field B, are set to select the precursor ions of a particular m/z. The precursor ions then dissociate or react in an electric field-free region between the two sectors. The ratio of the kinetic energy to charge of the product ions are analyzed by scanning the electric sector field E. The ...
The McLafferty rearrangement is a reaction observed in mass spectrometry during the fragmentation or dissociation of organic molecules. It is sometimes found that a molecule containing a keto-group undergoes β-cleavage, with the gain of the γ-hydrogen atom, as first reported by Anthony Nicholson working in the Division of Chemical Physics at the CSIRO in Australia.

The research also showed how certain genetic variants inherited from our Neanderthal ancestors, which make up between 1% and 3% of our genomes today, varied over time. Some, such as those related ...
A great deal of future research is required to isolate the parameters which are most significant for inducing the catagenetic process. Future work in the field will involve the following: Establishing the precise relationship between burial time and hydrocarbon cracking. Determining how hydrogen from water is ultimately incorporated in kerogen.
Congressional leaders dropped the text late Tuesday for legislation to stave off a government shutdown Friday night and keep the government's lights on through March 14, 2025, at current spending ...
A federal judge said Kraft Heinz must face a proposed nationwide class action alleging that it defrauded consumers by claiming its Kraft macaroni and cheese, one of its best-known products ...
