Thermal ionization - Wikipedia

Thermal ionization mass spectrometry (TIMS) is also known as surface ionization and is a highly sensitive isotope mass spectrometry characterization technique. The isotopic ratios of radionuclides are used to get an accurate measurement for the elemental analysis of a sample. Singly charged ions of the sample are formed by the thermal ionization effect. A chemically purified liquid sample is ...

Filament power regulator for thermal ionization mass ...

A mass spectrometer consists of three components: an ion source, a mass analyzer, and a detector. The ionizer converts a portion of the sample into ions. There is a wide variety of ionization techniques, depending on the phase (solid, liquid, gas) of the sample and the efficiency of various ionization mechanisms for the unknown species.

Thermal ionization - Wikipedia

Thermal Ionization Mass Spectrometry. To obtain high precise isotopic information from metal element systems, Thermal Ionization Mass Spectrometry is one of the most suited techniques. It consists of a thermal ionization source, where ions are generated and accelerated under vacuum, a magnetic sector where the ions get separated according to ...

TIMS: Thermal Ionisation Mass Spectrometry

A thermal ionization mass spectrometer consists of four main systems: an ion source, a beam collimator, a magnet and a detector, along with various subsystems including vacuum pumps, power supplies and computers.

Mass spectrometric measurements of copper isotopic ratios ...

Another similar ionization technique is to spray a surface with the ESI spray and have the spray extract ions from the surface into the mass spectrometer. This technique is called desorption electrospray ionization (DESI) and produces spectra similar to electrospray, but is analyzing the sample on a surface.

AbstractTwo new chemical abrasion thermal ionization mass spectrometry U/Pb dates establish the age of the top of the Brushy Basin Member, Morrison Formation, at Flat Top (also known as Terrace Hill), north of the Fruita Paleontological Research Natural Area (FP), and of the lower part of the Brushy Basin Member, in the region of the Trail through Time (TT) and Mygatt-Moore Dinosaur Quarry in ...

Improved three-filament thermal ionization mass ...

Mass spectrometry - Mass spectrometry - Thermal ionization: Atoms with low ionization potentials can be ionized by contact with the heated surface of a metal, generally a filament, having a high work function (the energy required to remove an electron from its surface) in a process called thermal, or surface, ionization. This can be a highly efficient method and has the experimental advantage ...
