A paper by Kazan Federal University and Tatarstan Academy of Sciences saw light in Physics Letters A. Ionization energy is one of the most important physicochemical parameters. It is defined in terms ...

The Vocus Flex incorporates interchangeable, drawer-style ion source modules that enable rapid switching between the VUV-based Vocus PTR Reactor and the fragmentation-free Vocus Aim Reactor. Automatic ...

Chemi-ionization reactions involve the formation of ionic products through the transfer of electrons during collisions between excited and ground-state species. These processes, which can occur in ...

Proton transfer reaction mass spectrometry (PTR-MS) and selected ion flow tube mass spectrometry (SIFT-MS) are well-established, field-deployable chemical ionization techniques known for their ...

Notes on good choices for MS techniques: Most service requests to an MS Lab are for “determining the molecular weight”. Most modern techniques ionize compounds by chemical reactions and the results ...

What is mass spectrometry and how does mass spectrometry work? MS is a form of chemical analysis used to measure the mass-to-charge ratio (m/z) of atoms and/or molecules in a sample. It is also ...

Bipolar ionization technology releases charged atoms that attach to and deactivate harmful substances like bacteria, mold, allergens, and viruses. It first arrived in the US in the 1970s as a tool to ...

In mass spectrometry, a sample is analyzed to determine its molecular composition through the generation of a spectrum that reveals the masses of its component parts. A transfer line introduces the ...

Ionization energy is one of the most important physicochemical parameters. It is defined in terms of the amount of energy required to rip an electron from an atom. The dependence of the ionization ...
