The use of linear quadrupoles in mass spectrometry as mass filters and ion guides is reviewed. Following a tutorial review of the principles of mass filter operation, methods of mass analysis are reviewed. Discussed are extensions of quadrupole mass filters to higher masses, scanning with frequency...
The development of the MPA has enabled the creation of the world's smallest residual gas analyzer, while offering the same or better sensitivity as conventional, larger mass spectrometers. The analyzer is a plug-in unit. It features a sensor unit that has already been calibrated for partial ...
Reference work2010,Encyclopedia of Spectroscopy and Spectrometry (Second Edition) Amy V.Walker Explore book Mass Analyzers There are three types of mass analyzer commonly used inSIMS:TOF,quadrupole(QMA/QMS), and double-focusing mass sector. To obtain elemental depth profiles, quadrupole and magnetic ...
In subject area:Chemistry A quadrupole is a type of mass spectrometry device that is versatile, robust, and commonly used in laboratories for high-throughput sample analysis. It consists of four cylindrical or hyperbolic metallic rods that separate ions according to their mass-to-charge ratio (m/...

Quadrupole Mass Spectrometry and Its Applications provides a comprehensive discussion of quadrupoles and their applications. It proceeds from a general explanation of the action of radiofrequency quadrupole fields to the description of their utilization in mass analyzers—such as the quadrupole mass filter...
Triple Quadrupole Mass Spectrometers (MS/MS) In tandem mass spectrometry (MS/MS) a first mass analyser selects an ion from a mixture, the ion is fragmented by collision, and a second mass analyser produces a spectrum of the fragment ions. MS/MS is used to determine ion structure and to ...
