Sindie+Cl TWO critical measurements, ONE push of a button, ZERO hassle

Sindie +Cl is a sulfur and chlorine analyzer delivering two critical measurements with one push of a button and zero hassle. It is the ideal solution for refineries and independent labs to certify sulfur levels in finished products and assess chlorine for corrosion mitigation, all with one instrument. Sindie +Cl utilizes a technique known as Monochromatic Wavelength Dispersive X-Ray Fluorescence (MWDXRF) – delivering exceptional reproducibility. Samples are measured directly, which means it can analyze even the heaviest of hydrocarbons like crude oil or coker residuals without the hassles of boats, injectors, furnaces, or changing detectors.

MWD XRF Monochromatic Wavelength Dispersive X-Ray Fluorescence (MWD XRF) utilizes state-of-theart focusing and monochromating optics to increase excitation intensity and dramatically improve signal-to-background over high power traditional WD XRF instruments.

This enables significantly improved detection limits and precision and a reduced sensitivity to matrix effects. A monochromatic and focused primary beam excites the sample and secondary characteristic fluorescence x-rays are emitted from the sample. A second monochromating optic selects the sulfur characteristic x-rays and directs these x-rays to the detector. MWD XRF is a direct measurement technique and does not require consumable gasses or sample conversion.

Application notes
Rapid and Accurate Analysis of Sulphur and Chlorine in Biofuels by XRF

With the continued development of biofuels and a push for higher concentrations in traditional fuels, petroleum professionals are looking to utilize technology that delivers rapid and accurate results for on-site biofuel measurement. Sindie +Cl is a viable solution, delivering total sulphur and chlorine in one measurement without the need for a matrix-matched calibration by simply applying a correction factor to the results. This allows professionals to certify their biofuel products more efficiently than with other methods. Sindie +Cl complies with ASTM D2622, and therefore meets the regulatory limit of ASTM D6751 and ASTM D7467. It also meets the precision requirements for ISO 20884 and can be used for EN 14214.

A Comparison of Chlorine Levels in Aromatics Using MWDXRF and Microcoulometry

When measuring aromatics, precision and accuracy at low concentrations are critical. From the ASTM data shown, MWDXRF analyzers, particularly Clora, demonstrate excellent accuracy when measuring samples against microcoulometry. The ability to measure total chlorines with minimal sample preparation and high performance, with results ready within minutes, is invaluable to refiners looking to protect their bottom line – and for these specific needs, Clora delivers on all fronts.
