The Sindie On-Line Analyzer is an industrial grade process sulphur analyzer with the breakthrough detection capability for monitoring fuel streams as exacting as ultra low sulphur diesel and gasoline. This process analyzer presents the ultimate solution for Pipeline Terminals, where measurement speed, and reliability are essential. The direct and non-destructive measurement technique (Monochromatic Wavelength Dispersive X-Ray Fluorescence) does not require sample conversion or consumable gases and does not involve high temperature operations. The result: a robust process analyzer with minimal maintenance and unprecedented detection capability and measurement speed.

Monochromatic Wavelength Dispersive X-Ray Fluorescence (MWD XRF) analysis provides a dramatically improved Signal/Background (S/B) ratio over conventional XRF techniques, in a compact and simplified on-line configuration. The improved S/B (LOD of 0,6 ppm) is achieved by eliminating the scattering from the x-ray source (x-ray tube).

The MWD XRF consist of an x-ray source (x-ray tube), a point-focusing optic for excitation, a sample cell, a focusing optic for collection and a x-ray detector. In this system, the first point-focusing optic captures a narrow bandwidth of x-rays from the source and focuses an intense monochromatic beam in a small spot on the sample cell. The monochromatic primary beam excites the sample and secondary characteristic fluorescence x-rays are emitted. The second collection optic collects only the characteristic sulphur x-rays which are focused onto the detector.
