In a triple quadrupole, the first quadrupole can be used to select a particular type of ion, which is then passed into a collision cell. The collision cell can be another quadrupole, as was the case ...

We consider multipole theory of linear constitutive relations for the macroscopic electromagnetic response fields D and H to electric octopole-magnetic quadrupole order. We use a recently developed ...

The Agilent 6400 Series Triple Quadrupole LC/MS Systems are the proven choice for your quantitative applications in pharmaceutical ADME/DMPK studies, biomarker validation, clinical research, food ...

The first “quadrupole topological insulator” has been created in a mechanical metamaterial by physicists in Switzerland. The experiment confirms a theoretical prediction made in 2017 that the concepts ...

Chromatographers looking for bold confidence in their samples can now benefit from a single quadrupole mass spectrometer designed for ease-of-use while offering application flexibility and reliable ...

To uncover the molecular composition of samples outside the lab, researchers have been shrinking mass spectrometers to make them portable. Various mass analyzers—the components of the spectrometer ...

Agilent Technologies Inc. has introduced a triple quadrupole gas chromatograph/mass spectrometer (GC/MS) and an updated triple quadrupole liquid chromatograph/mass spectrometer (LC/MS) at the American ...

Waters’ newest tandem quadrupole mass spectrometer is up to 15X more sensitive for analyzing negatively ionized compounds Xevo TQ Absolute is up to 45% smaller, uses up to 50% less power and nitrogen, ...

Our LC/QTOF-MS instrument (Agilent 6546) with the JetStream technology is one of the most accurate time-of-flight mass spectrometers in the market. It provides comprehensive screening for a large ...

IN the preceding note, which the Editor of NATURE has been good enough to let me see in advance of publication, Schmidt, following Murakawa 1, suggests that the frequent occurrence of perturbations in ...
