A HIGH RESOLUTION MULTICOLLECTOR ICP-MS

Geologian tutkimuskeskus (in English: the Geological Survey of Finland, "GTK") invites you to tender for the public contract according to the call for tenders, this Invitation To Tender ("ITT") and its appendices. A quotation is requested for: 1 (one) High Resolution Multicollector ICP-MS as defined in the tendering request attachments.

High Resolution Multicollector ICP-MS hardware • Being able to operate at least at three different resolution settings (from 300 to >9000). • Being able to analyse isotopes with a mass range from 4 to 300 amu. • A detector array with at least 11 Faraday cup detectors with extended dynamic range up to 100V, >20% dispersion and automated alignment. • 1011 Ω amplifiers for each Faraday detector. • At least three additional 1013 Ω amplifiers with extended dynamic range up to 1 V. • A centred Ion Counter with an automated switch from Secondary Electron Multiplier to Faraday detector. • A centred RPQ filter for improved abundance sensitivity. • An automated software controlled electronic gain calibration with amplifier specific calibration currents. • A built-in combination of reaction cell and pre mass filter (also called MS/MS) for the measurement of simultaneous isobaric isotopes, while separating other molecular interferences. • A complete sample inlet kit that includes a peristaltic pump, gas ports, Peltier water lines, SIS (Stable Introduction System) spray chamber, nebulizer, torch, injector, cones providing the optimum sensitivity and mass flow controllers for the torch, laser ablation and mass interferences correction devices. • A cooling system such as chillers for the magnet and the ICP interface. • The water-cooled magnet must provide a magnetic field stability better than 50ppm/hr. • A sensitivity higher than 1000V/ppm for Li, 850V Sr, 700V Nd, 1000V Hf, 1200V Pb and 1200V U in combination with a desolvating nebulizer with 100µl uptake. • Power computer with fast CPU, 16 Gb memory minimum, 500 Gb disk storage and two 27 inches monitors • Training session, either factory based or on-site • Shipping and Installation High Resolution Multicollector ICP-MS software • Integrating peripherals such as laser ablation system for automated applications and transient signal data processing, as well as nebulizer systems. • Capable of changing resolution settings • 3 additional copies of the analysis software to run analyses off-line
