IRIS INTREPID

▶ Improved high-resolution wavelength range, 165-1,000 nm.
The Intrepid's wavelength coverage begins at 165 nm, allowing determination of Al at the sensitive 167.081 nm line. The optional XUV configuration allows determination of Cl using the 134.724 nm line, while retaining the ability to measure K at 766.490 nm.

▶ Versatile plasma viewing capabilities.
Select full-range axial, full-range radial or automatic plasma viewing orientation. In the automatic mode, low wavelengths are measured axially while longer wavelengths are viewed radially. The system also allows you to select axial or radial view on a line-by-line basis, which ensures accurate results regardless of the matrix.

▶ Super-sealed optical bench. Reduced argon purge gas requirement lowers the cost of operation.
Quick-change, self-aligning torch mount. Rugged, pin-aligned torch mount allows rapid torch changeover. Unlike some systems that require readjustment whenever the torch is changed, you get perfect alignment every time!

▶ TraceTech ™ improves detection limits for all elements.
TraceTech, the first commercial axial plasma technology, developed by Thermo Elemental, simplifies high-sensitivity determinations in most matrices. The TraceTech design uses Thermo Elemental's unique long torch and counter-purged optical path, providing low background levels and low detection limits. The use of shear gas, which is known to cause a loss in low UV sensitivity is eliminated. The system's "Duo" option gives you two optical paths, so that the plasma may be viewed either axially or radially. It enables automatic changeover from axial to radial viewing over the entire wavelength range - even during sample analysis.

▶ High-performance Echelle optics.
The IRIS Intrepid series uses a simple, rugged, Echelle optical system with two dispersing elements - to provide a two-dimensional spectrum perfectly matched to the CID detector. Unlike a traditional spectrometer, which uses a very finely ruled grating, typically 1,000 to 3,000 lines/mm, the Echelle uses a grating with 45 to 70 lines/mm operated in high orders for high dispersion. This allows superior resolution and extended wavelength range within a compact optical enclosure. The simplicity of the design, with no moving parts, ensures analytical stability, long life and trouble-free operation.

▶ Complete range of configurations and accessories.
Additional functionality and convenience features as well as new-and-improved sample introduction systems let you tailor a system to fit any need. The new CrossTalk ™ built-in activation switch bank automates any custom sample handling device.

▶ CID: every wavelength from 165 to 1,000 nm.
The patented 262,000-pixel Charge Injection Device (CID) detector gives the IRIS Intrepid series more analytical capability than even the largest photomultiplier-based polychromators and the fastest sequential ICPs. With all analytical wavelengths available, you can select the optimal wavelength for each element in every sample type. Spectra can be stored in memory, then recalled

and reprocessed using different background correction points or internal standards to improve accuracy and precision - without having to rerun the samples. The exclusive Intelliframe ™ images contain all lines - without saturation - even for high-concentration matrix lines. Background correction measurements are simulta-neous with analytical readings, for improved accuracy and sample throughput. Several analytical wavelengths may be used for each element, providing proof-positive confirmation of accuracy.
