Updated Spectrotest Analyses Nitrogen and Carbon In Steel

Spectro Analytical Instruments presents a new version of the Spectrotest arc/spark-OES spectrometer at the Stainless Steel World America. The mobile metal analyser is even more flexible, with a smaller and more compact sample probe. Spectrotest is now able to tackle two new applications: the measurement of carbon in low alloy steel using arc discharge and the determination of the nitrogen content in duplex steels.

The most important innovation is the sample probe, which is considerably smaller, lighter and more compact than its predecessor.
With the reduced diameter of the sample probe it is possible to analyse sample surfaces in hard-to-reach locations, for example, bundled rods and bars. The standard probe can be used for quick grade identification with arc excitation as well as for a detailed analysis with spark excitation. The result is shown on the integrated display after only three seconds in the sorting mode; after five seconds in the analysis mode.

When the standard sample probe is exchanged with an optionally available special sample probe with integrated UV optic, the Spectrotest can also measure short wavelength elements like nitrogen. This makes Spectro the only manufacturer offering a mobile OES spectrometer for nitrogen determination. Performed without tools, exchanging the sample probes is quick and easy. Duplex steels are used mainly in plant infrastructure; the nitrogen content makes them extremely corrosion resistant.

The determination of the carbon content in low alloy steel with arc excitation is another new application for the redesigned Spectrotest. The identification of micro alloys in low alloy steel with arc excitation was also improved. A further optimised selection of element and reference wavelength pairs has helped to greatly improve analytical performance.

The range of use for the Spectrotest includes quality control in metal producing and metal processing companies, testing of finished products in industry as well as for scrap metal dealers and the control of plant infrastructure. With its fast measuring times, the metal analyser is especially suitable for metal processors with high volume production.
