Features of Triton Plus™ Multicollector Thermal Ionization Mass Spectrometer

High-Performance Ion Source and Optics 

  • Thermal ionization source with a very small kinetic energy spread (~0.5eV) means a single focusing geometry that focuses for angular divergence only is fully sufficient * 10kV ion source acceleration potential provides optimum sensitivity * Flight path baffles catch any diverging ions and minimize scattering at the side walls * Ion optics have been optimized for maximum ion transmission for both single and double filament techniques * Sample turret holds 21 single or double filaments that can be easily exchanged without tools 

    Flexible, Complete Collector Packages  Optimized collector packages are available for specific applications such as Os, Pb-U, U-series. Packages consist of application-dependent combinations of multiple electron multipliers, dual detectors (Faraday/electron multiplier) and RPQs. * High-performance Faraday cups are laser machined from solid carbon to guarantee uniform response, high linearity, low noise, and long lifetimes; they completely eliminate the need for cup factors * Virtual amplifier concept uses all amplifiers to measure all Faraday cup signals, effectively cancelling out all amplifier calibration biases and maximizing measurement precision * Tera-ohm feedback resistors improve signal-to-noise ratios two to three fold * Up to 10 current amplifiers with independent gains can be installed simultaneously * Software control of the amplifier/Faraday cup connections allows amplifier configuration to be configured to the needs of each experiment and its required precision * Multi-ion counting (MIC) arrays of discrete-dynode electron multipliers provide ultimate detection efficiency for small sample amounts * Up to eight discrete-dynode electron multipliers can be installed at one time 

    Sophisticated Software Control * Software supports fully automated sample manipulation and configurable and automated filament heating procedures * Automated pyrometer readout of filament temperature * Cup configuration editor is used to define and select cup configurations * Method editor enables the user to set up measurement procedures, including static, multidynamic, and fast single-collector peak jumping strategies, and sample heating programs * On-line and off-line data evaluation packages are available, including statistical capabilities and display of the results in spreadsheet or graphical form * User has access to all raw data and can monitor the results on-line during the analysis * Software allows a selection of the data to be evaluated and exported and also supports automated report generation of analytical results * Scripting language based on C programming language allows modification of existing procedures
