The IsotopX IsoProbe-T™ is a Multi-Collector Thermal Ionisiation Mass Spectrometer (TIMS) with a multiple-Faraday/Ion-Counting collector assembly for the precise determination of isotopic ratios.

IsotopX designers have created an instrument for a new era in Thermal Ionisation MS. The IsoProbe-T™ encompasses innovative, forward-thinking design, capitalising on over 33 years of experience amassed by IsotopX engineers.

The IsoProbe-T™ incorporates superior electronics, unique ion-optics and a wide flight tube for 20% relative mass separation in the static mode of collection. The M17 collector assembly is designed for total flexibility and incorporates field proven LIF™ Faraday collectors, together with the option of a multiple ion counting array, to measure isotope ratios at picogram sample sizes.

Over the past 40 years commercial Thermal Ionisation Mass Spectrometers have been continuously developed in response to changing customer requirements.  Improvements in ion source design have increased sensitivity, while advances in collector technology and software have increased to the point that accurate and precise measurements can be made on sub femtogram isotope abundances. 

The IsoProbe-T is the latest in a multi-generational series of mass spectrometers which have addressed the continuing analytical challenges posed by the nuclear and geological / environmental communities since 1971. The first instrument was the VG MM 30, and instruments such as the VG 54E, VG 354, VG Sector 54, Micromass IsoProbe-T, GV IsoProbe-T continued the tradition.

At the core of the IsoProbe-T is detector technology which combines very low noise Faraday collectors for the highest  <0.0005% (5ppm) precision isotope ratio measurements, with a comprehensive range of highly stable, multiple ion counting detectors, that can simultaneously measure for example the isotopes of Uranium and Plutonium in the smallest environmental samples. Simultaneous measurement means that all the ions are measured all the time, as opposed to a fraction of the time in sequential analysis. This is especially necessary for transient signal analysis in total evaporation measurements.

IsotopX will continue the tradition of providing the ultimate Thermal Ionization mass spectrometer.
