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 ...

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 ...

What are the ionization techniques for mass spectrometry? Mass spectrometry (MS) plays a vital role in many aspects of our lives, from diagnosing illness and detecting food contaminants to fighting ...

Ionization and coupling are two different sub-disciplines in the field of mass spectrometry. Ambient ionization allows direct, high-throughput, surface study of native samples. And for the study of a ...

Comprehensive two-dimensional gas chromatography (GC×GC) is a powerful tool which leads to dramatically improved separation for complex samples. This technique generates very narrow chromatographic ...

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 ...

Imagine doing a mass spectrometric analysis directly on your skin. With a new ionization method called desorption electrospray ionization (DESI), such an analysis could soon be possible on a routine ...

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 ...

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 ...

The Agilent 7890B is a state-of-art gas chromatograph (GC) that provides superior performance for all GC applications with the use of advanced electronic pneumatic control (EPC) modules and high ...
