Spectro Analytical Instruments has announced that its Arcos ICP-OES system can use a radial plasma configuration without compromising the detection limits needed for trace level measurements.
The Advanced Rowland Circle Optical System (Arcos) spectrometer employs an optical system that achieves the signal-to-background and resolution performance needed to take advantage of the radial plasma's better tolerance of high salt content (up to 30 per cent dissolved solids) or organics in the sample and its ability to handle slurries or suspensions.
The design of the optical system achieves, with few reflections, 8.5 picometer resolution in the vital UV region and the high energy throughput to exploit it.
Spectro's UV-plus system requires no purge gas supply or vacuum pumps for UV performance, as the sealed optical path is permanently filed with Argon.
An array of 32 linear CCD detectors allows a full spectrum from 130-770nm to be collected and stored in under two seconds using less memory than conventional systems.
Unlike many CCD-based detection systems, no sub-ambient cooling is required.
An axial system can also be supplied.
