The Z-200 C+ is a dedicated analyzer for alloy analysis including carbon content. It analyzes carbon content in stainless, down to 0.007 ppm, for dependable separation of L and H grades. The C+ also analyzes carbon steels, including carbon equivalents (CE) for weldability. The analyzer is available in two versions. The Z-200 C comes with iron-base calibrations including carbon. The Z-200 C+ includes both iron and stainless bases and carbon. Additional bases may be added at time of purchase or any later date. Following in the tradition of our defy obsolescence principle, any Z-200 or Z-200 C may be upgraded to the Z-200 C+ at any time for the price difference.

The Z uses the technique laser induced breakdown spectroscopy (LIBS), which has many similarities to spark OES. LIBS has been an established laboratory technique for 20+ years. It fires a pulsed laser at the material to create a plasma, instead of a continuous electric spark like spark OES. Light from the plasma is measured with an on-board spectrometer to determine individual wavelengths and thus what elements are present. The elemental content is quantified via onboard calibrations.

High resolution is critical. The Z-200 C+ is equipped with a dedicated third spectrometer optimized for the best wavelength resolution around the carbon line. Due to the many nearby iron lines, resolution better than 0.080 nm is a must. Powerful laser – onboard argon purge – high resolution spectrometer. It’s the key to rock solid, in-field carbon analysis for alloys.
