From gasoline to ethanol and toluene, the Signal benchtop analyzer delivers unprecedented precision and accuracy in quantitative analysis of silicon in petroleum. The analyzer is based on XOS’s MWDXRF technology platform (as applied in Sindie® and Clora® analyzers) ensuring a robust analysis solution for demanding petroleum and industrial evironments.
Silicon (Si) contamination continues to impact fuel quality, resulting in costly engine failures and catalyst fouling. ASTM test method D7757 compliant, the Signal uses proven, state-of-the-art technology to provide exceptional Si analysis.
Know the contamination sources and develop working solutions.
Understand the impacts of Si contamination on your business.
Determine your Si baseline for future specifications set by ASTM or the end user.
MWD XRF
Monochromatic Wavelength Dispersive X-Ray Fluorescence (MWD XRF) utilizes state-of-the-art focusing and monochromating optics to increase excitation intensity and dramatically improve signal-tobackground 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 silicon 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.
