MESA-7220V2*

X-ray Fluorescence Sulfur/Chlorine-in-oil Analyzer

The MESA-7220V2 measures both sulfur and chlorine in petroleum based products using the Monochromatic EDXRF method. A monochromatic X-ray source is used in order to obtain an ultra-low noise background which affords the best detection limits for both sulfur and chlorine.

The detector window size was increased to collect more fluorescent X-rays and thus achieve lower level ppm values. This provides excellent, repeatable performance at both low and high concentrations of both elements.

By adjusting the angle of the graphite crystal, the excitation beam can be measured to excite sulfur in the sample, increasing sensitivity.
