HORIBA Scientific
Ultima Expert
ICP-OES, Inductively Coupled Plasma Optical Emission Spectrometry
Sub-5 pm resolution and full 160–800 nm coverage for the most demanding elemental analysis.
The Ultima Expert is a radial-view ICP-OES spectrometer built for laboratories where difficult matrices are routine rather than exceptional. Its one-metre focal length optical bench and high-density holographic grating deliver resolution below 5 pm across the deep UV, which is what allows line-rich spectra from iron, tungsten and rare earth matrices to be separated cleanly.
Rather than switching between axial and radial geometries, the instrument observes the full normal analytical zone in a single radial configuration. The practical consequence is consistent sensitivity across high-salt, brine, high-dissolved-solids and organic samples without the matrix compromises that view-switching usually imposes.
Climax Scientific supplies, installs and supports the Ultima Expert as an authorised HORIBA partner. Configuration depends on your matrices, throughput and regulatory environment, so specifications below describe the standard build; contact us to discuss the configuration appropriate to your laboratory.
