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 ...

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 ...

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 ...

Ambient mass spectrometry (ambient MS) 1 is an extension to MS that allows the analysis of samples at atmospheric pressure under ambient conditions. In ambient MS, samples are exposed to agents that ...

To achieve the best results, using the right ionization method is essential. There are three main atmospheric pressure ionization (API) techniques that differ in their application concerning compound ...

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 ...

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 ...

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 ...

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 ...
