Carbon. They said it couldn’t be done

Gammatec NDT Supplies SOC Ltd3, Vereeniging, Gauteng, South Africa

Introducing the new SciAps Z200C+

Check out the world’s only handheld analyzer that measures carbon content in stainless (yes, even L-grades), steel and cast iron. The Z-200C+ is also accepted for low Si analysis for sulfidic corrosion analysis, and is widely used in the power industry for Cr analysis, for flow accelerated corrosion (FAC) applications. Now there’s a handheld analyzer for carbon content, general alloy PMI/NDT, sulfidic corrosion and FAC.

The Z-200 C+ uses the technique of laser induced breakdown spectroscopy (LIBS). LIBS is an optical emission technique, quite similar to spark OES, except the electric spark source is replaced by a miniature pulsed laser. The laser is focused onto the metal surface to create the plasma. An on-board spectrometer collects the various wavelengths of light, and applies intensity ratio-based calibrations to quantify content of carbon and other alloying elements. Because the laser beam is focused down to <100μm, the volume required for argon purge is much smaller than spark OES. The argon supply can therefore be stored in the handle of the analyzer, and is user-replaceable.
