The electrostatic quadrupole lens, quadrupole accelerator and square rainbow lens as well as radio frequency quadrupole accelerator all have similar structure with four rod-like electrodes. Unlike the ...

Stacking interactions are a recurring motif in supramolecular chemistry and biochemistry, where a persistent theme is a preference for parallel-displaced aromatic rings rather than face-to-face ...

A uniformly twisted quadrupole structure produced by point matching of electrostatic potential by Robert Gordon McPherson Publication date 1976 Collection ualberta_theses; ...

Abstract:The design of a miniature quadrupole lens based on metallized glass electrodes mounted in two anisotropically etched silicon mounts that are separated by precision spacers is described. The ...

The quadrupole mass analyzing device is now accessible to many analytical chemists as a detector in either HPLC or GC instruments due to their increasingly accessible price point. While it’s not vital ...

What are the common types of mass analyzer? At the heart of any mass spectrometer is the mass analyzer. This component takes the ionized masses and separates them based on their mass-to-charge ratio ...

To gather these measurements Beckers et al. used an Electrostatic Quadrupole Plasma (EQP) analyzer. “Normally, this type of EQP already is able to measure in a temporally resolved fashion but is way ...

Impact of molecular quadrupole moments on the energy levels at organic heterojunctions. Nature Communications, 2019; 10 (1) DOI: 10.1038/s41467-019-10435-2 ...

Recently several molecular mechanics models of halogen bonding have been published. They describe the electrostatic potential anisotropy near the heavy halogen atom (known as a σ-hole) in different ...
