Novel multichannel plasma-source mass spectrometer

Multichannel grazing-incidence spectrometer for plasma impurity diagnosis: SPRED.

A compact vacuum ultraviolet spectrometer system has been developed to provide time-resolved impurity spectra from tokamak plasmas. Two interchangeable aberration-corrected toroidal diffraction gratings with flat focal fields provide simultaneous coverage over the ranges 100-1100 A or 160-1700 A. The detector is an intensified self-scanning photodiode array. Spectral resolution is 2 A with the ...

A Benchtop Inductively Coupled Plasma Mass Spectrometer

Inductively coupled plasma mass spectrometry (ICP-MS) is an analytical technique that performs elemental analysis with excellent sensitivity and high sample throughput. The ICP-MS instrument employs a plasma (ICP) as the ionization source and a mass spectrometer (MS) analyzer to detect the ions produced. It can simultaneously measure most elements in the periodic table and determine analyte con...

MEMS ion source for mass spectrometer integrated on a chip

A novel high-capacity ion trap-quadrupole tandem mass spectrometer.

We describe a prototype tandem mass spectrometer that is designed to increase the efficiency of linked-scan analyses by >100-fold over conventional linked-scan instruments. The key element of the mass spectrometer is a novel high ion capacity ion trap, combined in tandem configuration with a quadrupole collision cell and a quadrupole mass analyzer (i.e. a TrapqQ configuration). This ion trap ca...
