The Spectrotest TXC25 high-performance, mobile metal analyzer is capable of rapidly determining the nitrogen content in duplex steels with a spark excitation, and quickly identifying low-alloy steels using carbon excitation. The unit’s thin sample probe enables hard-to-reach sample areas, such as bundled rods and bars, to be easily analyzed. The device 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 probe that is integrated with ultraviolet optics, the analyzer is able to measure elements such as N, B, C, P and S. A minimum difference in the nitrogen content of 500 ppm is necessary. — Spectro Analytical UK Ltd., Leicester, U.K.
