Features of Neptune Plus™ High Resolution Multicollector ICP-MS
Jet Interface for Ultimate Sensitivity
The jet interface increases sensitivity 10-20 times across the entire mass range in desolvation mode.
High-Resolution Double-Focusing Analyzer * 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
Fully Flexible Detection System * 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
Sophisticated Software Control * 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
