• Optional semi and fully-demountable torches with choice of glass or ceramic injector tubes, high solids torch and all-glass sample introduction system.

Gas control

• Plasma and auxiliary gas flows are software controlled using switched flow controllers. The system is fully interlocked against gas failure.
• Nebulizer gas: software enabled with choice of flow control using a high precision pressure regulator, or computer controlled using mass flow control. MFC provides fl ow range 0–1.3 L/min in 0.01 L/min increments
• Plasma gas: 0–22.5 L/min in 1.5 L/min increments
• Auxiliary gas: 0–2.25 L/min in 0.75 L/min increments

RF generator

• 40 MHz free-running, air-cooled RF generator. Power output of 700–1500 W in 50 W increments. Optimum power settings defined and stored within each method for different sample types
• Over 75% RF coupling efficiency
• Automatic ignition and shutdown with user-customizable ignition sequence
• Power output stability is better than 0.1%

Plasma configuration

• Radially viewed system (715 ICP-OES)
  Vertically oriented, radially viewed plasma is ideal for the most difficult of applications, including the analysis of oils and organic solvents, geological/metal digests and high TDS solutions e.g., brines. Includes full PC control of plasma viewing height from 0-20 mm and horizontal adjustment of ±3 mm to optimize sensitivity and minimize interferences. Viewing height may be adjusted under PC control for each wavelength of interest.
• Axially viewed System (710 ICP-OES)
  Horizontally oriented, axially viewed plasma is ideal for high sensitivity analyses. Provides a 2–8 fold improvement in detection limits compared to radial viewing. The axially viewed plasma system features a unique Cooled Cone Interface (CCI) to prevent the cooler plasma tail from being viewed by the optics. This reduces interferences, improves the system’s tolerance to high dissolved solids and extends the linear dynamic range compared to conventional axial systems. The CCI is a superior plasma interface with lower running costs compared to shear gas systems. Includes full X, Y adjustment of plasma viewing position under PC control.

 Optical system

• Computer-optimized echelle optical design with no moving optical parts ensures lowest detection limits and maximum stability
• 400 mm focal length polychromator is thermostatted to 35 °C for excellent stability. Features a precision prism cross disperser and echelle grating (94.74 lines/mm) creating an echellogram (of 70 orders) that is projected onto the megapixel CCD detector
• Standard polychromator purge of 0.75 L/min with PC controlled 3 L/min boost purge for operation with emission lines having wavelengths below 185 nm. Can be purged with either argon or nitrogen (requires optional nitrogen purge kit)

Megapixel CCD detector

• Innovative megapixel CCD detector features 1.12 million pixels, each 15 ìm x 15 ìm in an X-Y grid array for full wavelength coverage from 177 nm to 785 nm. The detector is thinned and back illuminated for enhanced Quantum Efficiency (QE) in the UV.
• The detector is mounted on a two stage Peltier device and cooled to -30 oC for low dark current and noise
• Auto Integration allows intense and trace signals to be measured simultaneously at the optimum signal-to-noise ratio, providing lowest possible detection limits and preventing over-range signals – more intense peaks are allocated shorter integration times and less intense peaks are allocated longer times
• The megapixel CCD detector features anti-blooming protection on each pixel. This enables the simultaneous measurement of trace level analytes in the presence of nearby intense signals.

Instrument software features

• ICP Expert II is an easy-to-use, web-integrated instrument software package. It features wizards that guide users through method and sequence development and method templates for rapid development of commonly used methods.
