Finnigan Mat 262
Purified samples are thermally ionized by passing a current through a thin metal filament or filaments.
Finnigan mat 262. Counting efciencies close to 100 were achieved by operating the channeltrons at 2000 v for negative ions about 200 v higher with dark currents 0 1 counts s 1. One adjusts the magnetic field strength another adjusts the electrostatic field strength and a third controls the tutorial speed. 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. Thermal ionization mass spectrometry tims is used for very precise isotope ratio measurements.
Manufacturer thermo fisher scientific. The mat 95 xp is a highly flexible gc ms system fully automated regardless of injector type and offers multicolumn operation as a standard feature. The ions enter the first magnetic analyzer where they interact with the magnetic field and are sorted by mass before a select group of one. Finnigan mat 262 tims.
Finnigan mat 253 stable isotope ratio mass spectrometer isodat software suite isodat is the software suite for system control data acquisition and data evaluation. Our instrument solutions enable our customers to make the world a healthier cleaner and safer place. Here we report first experiences with a modified mat 262 equipped by finnigan mat with such channeltrons in five of the six variable faraday collector positions. The thermal ionization mass spectrometer is used for high precision isotope ratio measurements.

Finnigan mat 262 tims. Ions of different masses denoted by different colors stream through the machine. You can manipulate three sliders. 10 ppb has been achieved with the redesigned retarding potential quadrupole rpq ii on the finnigan mat 262 test instrument at the finnigan mat applications laboratory and on the instrument installed at the open university.
The open university instrument is equipped with a deflection unit after the rpq ii to select a faraday collector or a secondary electron. It is an integral part of the system architecture and enables the analytical power and flexibility of the finnigan mat 253 to be routinely brought to bear on solving the toughest. An abundance sensitivity of lt. Be the first to review this product.
The design philosophy of the mat 252 was e no compromises e with the aim of delivering ultimate performance. Mass resolved ion beams.
