Speedy Spectrometer

Near the end of January, SPECTRO Analytical Instruments announced the first spectrometer that allows users to quickly and easily select axial plasma or radial plasma observation in a single instrument without any optical compromise—the ARCOS.

New Instrument Allows Easy Switching to and from Axial Plasma or Radial Plasma Observation

In a release, the company stated that the ARCOS “easily surpasses the performance limitations of conventional ICP-OES instruments—dramatically improving sensitivity, stability, and precision, while lowering operating costs with the introduction of innovative components, unique capabilities, and optimum flexibility.”

The company added that the instrument establishes a new ICP-OES performance class for complex analytical tasks that resolves a wide array of the problems inherent in traditional spectrometer design.

Key features of the new spectrometer include a unique MultiView capability, which is what allows simple switching between axial plasma and radial plasma observation and also improves stability and accuracy, and the ORCA optical system. That system “delivers a matchless resolution of 8.5 picometer in the wavelength range from 130 to 340 nm,” according to SPECTRO.

The ARCOS also includes a solid-state power generator design that provides the highest plasma power available for extreme or quickly-changing plasma loads and its UVPLUS sealed optical chamber ends the need for the purging of argon or nitrogen gases—along with the related supplies, maintenance costs, and downtime. Lastly, air-cooled interface technology and the completely air-cooled generator eliminate the need for an external cooling system, along with the associated costs of such a system.
