Spectro Analytical has introduced a mobile metal analyser that can determine the nitrogen content in duplex steels with spark excitation and identify low-alloy steels using carbon in arc excitation.
The Spectrotest TXC25's compact, thin sample probe enables hard-to-reach sample areas - such as bundled rods and bars - to be analysed.
The lightweight device is suitable for steel stockists, importers, metal recyclers and quality control in metal-producing and metal-processing companies.
The mobile metal analyser's flexibility also makes it a suitable instrument for testing finished products in industry.
The instrument can be used cordlessly with a rechargeable battery pack.
Capable of high sample throughputs, the Spectrotest TXC25 is able to quickly identify austenitic and so-called duplex alloys where nitrogen is the only differentiation compared to other stainless or high-alloyed steels.
By exchanging the standard sample probe with an optional special sample probe with integrated ultraviolet optic, the analyser is able to measure elements such as nitrogen, boron, carbon, phosphorous and sulphur.
A minimum difference in the nitrogen content of 500ppm is necessary.
Exchanging the sample probes is said to be quick and simple.
The instrument, which can handle the analysis of all aluminium grades, can also simplify the carbon analysis of L-grade stainless steels in spark mode.
The mobile metal analyser's 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 three seconds in grade ID mode and after five seconds in the analysis mode.
The analyser features an integrated array of temperature-stable optical components and offers ICAL, a single sample standardisation irrespective of the number of calibrations installed.
