Polychromator:
- The high-energy (f/6.7) echelle-based Optima™ polychromator utilizes one or two SCD detectors depending on the Optima model.
- The 80 by 160 mm echelle grating has 79 lines per mm and a blaze angle of 63.4 degrees
- In the Optima 7300 DV, a 60-degreefused-quartz prism is added as the cross-disperser for the visible region (403-782 nm). The Optima 7200 DV includes a single cross-disperser with dual dispersion (374 and 187 lines/mm, computer-controlled shutter selectable) to cover the full UV region (163-403 nm) and selected parts of the visible region (421 nm, 610 nm, 670 nm and 766 nm).
- The UV disperser on all Optima 7x00 DV series spectrometers incorporates Schmidt correction to eliminate aberration for the 400-mm radius camera sphere.
Parameters: The measured resolution of the system is 0.006 nm at 200 nm
Dual-view optics:
- Viewing of the plasma is accomplished by computer control of a mirror located in the optical path and allows selection of axial, radial or mixed viewing modes and adjustment of the plasma viewing in both the vertical and horizontal planes.
- The viewing position can be optimized by the software.
Detector:
- Custom-designed, application-specific, patented PerkinElmer Segmented-array Charge-coupled Device detectors or SCDs consist of 235 addressable subarrays covering approximately 6000 wavelengths on a 13 by 19 mm silicon substrate
- Typical readout noise is about 13 electrons RMS; dark current is less than 100 electrons/pixel/second; and readout speed is 50 µsec/pixel
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.
Shutter and Hg recalibration system:
- The computer-controlled, pneumatically operated shutter automatically opens and closes for each sample, protecting the first transfer mirror from long exposures to the intense UV radiation of the plasma, extending the useful lifetime of the mirror.
- A mercury lamp is built into the shutter mechanism and can be viewed at a user selected frequency to automatically update the system wavelength calibration at the 253 nm mercury emission line.
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: Instruments can be ordered with a Ryton®HF-resistant Scott-type or a glass cyclonic spray chamber. An optional spray-chamber compartment thermostat is available for laboratories with minimal air conditioning.
Nebulizers: The Optima 7x00 DV systems can be ordered with a cross-flow or glass concentric nebulizer. Additional nebulizers are available.
Power: One 200-240 V, 20A line, single-phase, 50/60 Hz
Dimensions: 150 x 76 x 89 cm (W x H x D), 200 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.
