Replace current ICP-MS with the new generation of ICP-MS that is built for total reliability, advanced performance and assured accuracy. A design inspired by real laboratory needs simplifies the user experience and dramatically improves productivity and efficiency. This innovative single quadrupole (SQ) ICP-MS analyzer is the ideal solution for a wide range of sample types and industries; from demanding 24/7 routine analysis to advanced applications in research. User-friendly manages entire workflows from `Get Ready¿ to data reporting. Sample introduction The bench height sample introduction system is positioned to optimize user access to all parts.

Spray chamber Peltier cooled high purity quartz or PFA, low-volume, baffled cyclonic spray chamber, efficiently filters out larger aerosol droplets for improved plasma stability. Reduced surface area improves sample washout. Compatible with all 6 mm OD nebulizers. Nebulizer High performance, concentric nebulizers with ~0.4 mL·min-1 sample consumption. Optional nebulizers in a range of flow rate sizes, total dissolved solids tolerance and suitability for organics or HF. Torch Push-in, demountable single piece quartz torch. All connectivity (argon gas supplies and plasma ignition) designed into the holder, reducing torch complexity and improving usability. Proprietary, screw-in, self-aligning injector for ease of use and reliability. Peristaltic pump Compact, low pulsation, 12 roller, four channel mini-pump with inert rollers for improved reliability. Additional gas kits Two additional mass flow controllers (0-250 or 0-1000 mL·min-1) available as options. Coupled closely to the sample introduction system with quick fit connectivity. Fully software controlled allowing for the introduction of gases into the spray chamber (e.g. O2 for the analysis of organic solvents or Ar for Gas Dilution) or to supply gases for coupled accessories (for example He during Laser Ablation). Inductively coupled plasma The proposed ICP-MS plasma is designed to rapidly adapt to changing matrices and provide unparalleled robustness even for challenging samples such as highly volatile organic solvents. RF generator Digital, solid-state RF generator operating with dynamic frequency impedance matching the plasma at ~27 MHz. Low ion energy spread for optimum ion focusing and transmission, without the need for a grounded shield between the torch and load coil. Highly stable and robust cold plasma operation. Load coil Water-cooled load coil for an improved lifetime and reliable plasma ignition. Accessible at bench height for ease of maintenance. Plasma TV Remote monitoring of plasma status via integrated HD camera. Interface The unique front opening interface provides rapid, simultaneous access to cones and extraction lens, to facilitate routine maintenance and minimize downtime. Cones Optimized sample (1.1 mm diameter orifice) and skimmer (0.5 mm diameter orifice) cone geometries for reduced matrix deposition and maintenance. Ni cones as standard; Pt tipped as an option for specialized applications. Cones are rapidly removed by a single (magnetic) tool. Proprietary skimmer insert design reduces memory effects and a range of inserts allows the user to balance the needs of matrix resistance against absolute sensitivity. Robust Interface specifically designed for minimal drift during a long-term analysis of high matrix samples. High Matrix Interface for typical sample types provides the optimal balance between sensitivity and tolerance. High Sensitivity Interface provides an excellent signal to noise ratio for ultra-trace analysis and advanced applications. Extraction lens Single extraction lens operated at low voltages for optimum ion extraction and focusing into the ion optics bayonet mounted for easy handling. Slide valveSoftware controlled: defaults to the closed position when plasma is off or in the event of a power failure, maintaining the vacuum in the analyzer housing Ion optics Unique 90° cylindrical ion lens ¿ the RAPID lens: Right Angular Positive Ion Deflection, providing high ion transmission across the entire mass range. RAPID lens dimensions significantly larger than ion beam and neutrals eliminates lens cleaning maintenance. Off-axis design delivers class-leading background noise. Electrical connections with gold spring contacts from the analyzer housing to ions optics improve reliability. QCell collision/reaction cell (CRC) Zero maintenance, small volume collision/reaction cell with proprietary flat-pole rods. High transmission, even in He KED mode, enabling complete single measurement mode analysis of all analytes including Li and Be. Low mass cut off for improved interference reduction than KED alone. Choice of 1 or 2 gas specific mass flow controllers for He and flexibility to work with reactive gases such as H2, O2, or a mixture of NH3/He. Quadrupole Quadrupole mass analyzer is driven by a solid-state, 2 MHz supply ensures low abundance sensitivity and class-leading mass stability. User-definable mass resolution in the mass range 2-290 u (enabled with intelligent Mass Resolution (iMR)). Mass calibration assessed and automatically updated. Vacuum system High vacuum is maintained in the event of a power failure: the rotary and turbo pump automatically restart as soon as power is restored. A stable vacuum, obtained in less than 15 minutes pumping time, enables fast return to service after routine maintenance. Turbopump Single split-flow turbo molecular pump. Interface pump External, high-performance pump to provide backing to the turbopump and evacuation of the expansion region for improved sampling from the plasma. Supplied with synthetic, chemically stable, temperature resistant rotary pump oil as standard. Detector Long lifetime detector designed for ICP-MS requirements. Dwell times of 100 ¿s in both analog and counting detection modes. Linear dynamic detection range: > 10 orders of magnitude. Automated optimization of operating voltages and cross-calibration. Cradle design for ease of detector exchange.
