Double spectrometer:
-      The Optima 7000 DV ICP-OES uses a unique double-spectrometer optical system.
-      This design results in a high-speed, high light-throughput optical system offering excellent resolution, all in a compact system.
-      The sealed optical system can be purged with nitrogen for low UV (160-190 nm) performance.
Parameters: The spectral range is 160-900 nm with resolution of < 0.009 nm at 200 nm.
Dual-view optics:
-      The system includes complete dual-viewing optics under computer and software control.
-      Any wavelength can be used in the radial, axial or mixed viewing modes in a single method.
-      Viewing of the plasma is accomplished by computer control of a mirror located in the optical path and allows selection of axial or radial view and adjustment of the plasma viewing in both the vertical and horizontal planes.
Dynamic wavelength correction:
-      The wavelength reference section of the detector monitors a full wavelength neon spectrum, creating a dynamic wavelength scale used to actively correct wavelength positions.
-      The resulting wavelength accuracy and reproducibility allows direct ‘on-peak’ measurements rather than time-consuming peak-search methods used in sequential ICP systems.
Detector:
-      UV-sensitive, dual backside-illuminated CCD array detector
-      Cooling: using a single-stage integrated Peltier cooler operated at approximately -8 °C
-      Having two photosensitive segments containing 176 by 128 pixels: One section is used for analytical measurements, and the other is a wavelength reference section.
-      Collecting both the analyte spectra and the nearby background spectra, allowing for simultaneous background correction and providing improved precision and analytical speed.
RF generator:
-      Second-generation 40-MHz, free-running, solid-state RF generator
-      Adjustable from 750 to 1500 watts, in 1-watt increments
-      The power efficiency: greater than 81% with < 0.1% variation in output power stability
Shear gas:
-      A compressed-air shear gas (18-25 L/min) is used to remove the plasma tail from the optical path, minimizing interferences and extending the dynamic range.
Torch/torch mount: A unique, quich-change and demountable torch design with 2.0 mm standard alumina injector. A variety of other injectors is available. No tools are required for torch or sample-introduction removal.
Spray chambers: A Scott spray chamber made from inert Ryton® for complete corrosion resistance to most acids, including HF and the glass cyclonic spray-chamber based system for use with high dissolved solids solution or with organics is also available.
Nebulizers: The Optima 7000 DV systems can be ordered with a cross-flow or glass concentric nebulizer. Additional nebulizers are available.
Power: One 200-240 VAC, 30A line (9 amp draw at 240 V), single phase, 50/60 Hz (±1%)
Dimensions: 132 x 81 x 76 cm (W x H x D), 125 kg
Environmental: The instrument will operate with a laboratory temperature between 15 and 35 °C (59-95 °F). For optimum instrument performance, the room temperature should be controlled at 20 ±2 °C.
