Neptune Plus

Meet the ever-expanding application demands of earth sciences and other fields requiring high-precision isotope ratio measurements with the Thermo Scientific™ Neptune Plus™ high resolution multicollector ICP-MS system. The Neptune Plus system combines field-proven technology with the latest innovations in amplifier technology. This powerful double-focusing mass spectrometer, with high mass resolution, variable multicollectors, and multi ion counting capability, offers ground-breaking sensitivity, high dynamic ranges, unsurpassed linearity, and robust stability.

• The jet interface increases sensitivity 10-20 times across the entire mass range in desolvation mode.

• ICP interface improves resolution, reducing the initial kinetic energy spread by capacitively decoupling the plasma from the load coil
• Double-focusing mass analyzer focuses both ion energy and angular divergence for superior mass resolution
• Independent source and detector slit settings enhance mass resolution by separating molecular interferences from elemental peaks
• Wide detector slit in all resolutions guarantees the widest peak flatness at high resolving powers, a prerequisite for highly precise and accurate isotope ratio analyses
• Low, medium and high resolution settings can be selected with a single mouse click

• 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
• 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
• Available retarding potential quadrupole (RPQ) lenses improve abundance sensitivity by one order of magnitude to <500 ppb
• 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

• Software allows a fully automated plasma-ignition sequence
• Cup configuration editor is used to define cup configurations
• Method editor enables the user to set up measurement procedures, including static, multidynamic, and fast single-collector peak jumping strategies
• On-line and off-line data evaluation packages are available, including statistical capabilities and display of the results in spreadsheet or graphical form
• Users have access to all raw data and can monitor the results online during the analysis. The software allows data to be evaluated and flexibly exported; ideal for laser ablation applications.
• Sequence editor provides automatic, unattended acquisition and evaluation of samples including sample/standard bracketing and blank subtraction
• Triggering of, or triggering from coupled devices, e.g. from a laser system, is fully supported
• Automated report generation of analytical results is included
• Scripting based on the C programming language allows modification of supplied procedures.
• For GC and HPLC applications, additional software package dedicated to the evaluation of transient signals are available
