Finnigan Mat 262 Tims

Thermal ionization mass spectrometry tims is used for very precise isotope ratio measurements.

Finnigan mat 262 tims.

Finnigan mat 262v tims. Purifications of nd and sm were carried out using the methods described by ref. The thermal ionization mass spectrometer is used for high precision isotope ratio measurements. Purified samples are thermally ionized by passing a current through a thin metal filament or filaments.

Thermal ionization mass spectrometry tims with samples loaded on metallic filaments for vaporization and ionization before mass analysis has been the mainstay analytical technique for precise isotope ratio. See the complete list of deadlines. Evolving goals of safeguards environmental sampling of uranium and plutonium demand decreased sample sizes. Finnigan mat 262v tims.

57 and their abundances were determined by tims finnigan mat 262 and thermo finnigan triton for nd and by the mc. Thermal ionization mass spectrometry tims is used for very precise isotope ratio measurements. The tims uses 8 faraday collectors and a sem ion counting system and is used in isotope geochemistry and geochronology applications. Finnigan mat 262 tims.

The finnigan mat 253 stable isotope ratio mass spectrometer system delivers the highest precision for the determination of d h 13c 12c 15n 14n 18o 16o 34s 32s from so2 and sf6 28si 29si as well as ar kr and xe isotope ratios. Finnigan mat 262 tims. The thermal ionization mass spectrometer is used for high precision isotope ratio measurements. The values of filament temperature and the respective heating current are given in the diagrams.
