A mass spectrometry method comprising steps of generating an ion beam from an ion source; directing the ion beam into a collision cell; introducing into the collision cell through a gas inlet on the collision cell a charge-neutral analyte gas or reaction gas; ionizing the analyte gas or ...

Finally there was the introduction of multisector instruments which gave rise to the technique of mass spectrometry-mass spectrometry (MS-MS). CID has proved very useful in assigning structures to fragment ions. View chapterExplore book Physical modelling and advanced simulations of gas–liquid two-...
The unimolecular chemistry of Fe{sup +}-benzyne and its reactivity with small alkanes in the gas phase are studied by Fourier transform mass spectrometry (... Y Hayashibara - Journal of the American Chemical Society; (USA) 被引量: 38发表: 1989年 Control of ion kinetic energy in ion cyclotr...
Define collisionally. collisionally synonyms, collisionally pronunciation, collisionally translation, English dictionary definition of collisionally. n. 1. An act of colliding; a crash. 2. A condition of opposition or conflict between two or more people
Native mass spectrometry (MS) of proteins and protein assemblies reveals size and binding stoichiometry, but elucidating structures to understand their function is more challenging. Native top-down MS (nTDMS), i.e., fragmentation of the gas-phase protein, is conventionally used to derive sequence ...

We describe the interpretation of ion mobility data in terms of protein conformation and how the data can be compared with data from other sources with the use of computational tools. The benefit of coupling mobility analysis to activation via collisions with gas or surfaces or photons ...
A method for simultaneous determination of solubility and transfer coefficient of oxygen in aqueous media using off-gas mass spectrometry A static method was developed that simultaneously determined the solubility of oxygen and the oxygen-transfer coefficient in a stirred bioreactor. It was b... RC ...
Electrospray ionization-mass spectrometry (ESI-MS) is a technique able to preserve the non-covalent interactions of protein–ligand complexes in the gas phase [1, 2, 3]. Since its original discovery, the application of ESI-MS in this area has accelerated rapidly [4, 5]. The ESI-MS approac...
