Why does the resolution matter?
In line-rich spectra, nearby signals can compromise identification and quantification. High resolution helps separate these signals, expand wavelength options and build more robust methods.
This is especially relevant for rare earths and materials of complex composition.

Technical information
Why is ULTRA Expert suitable for rare earths?
High-resolution optics help separate nearby lines and reduce the impact of frequent spectral interference on complex rare earth matrices.
Does the equipment serve water and effluent?
Yes. The ICP-OES HORIBA can be configured for multi-element analysis of water and effluents, considering method, preparation, calibration, bands and appropriate accessories.
Does ICP-OES analyze solid materials directly?
Not in conventional configuration. Solid materials usually require digestion, fusion followed by dissolution or other compatible preparation.
Can the ULTIMA Expert handle high dissolved-solids content?
Radial observation and the Sheath Gas feature help extend the tolerance to matrices with higher dissolved solid content, always according to configuration and method.
