MWD XRF Analyzers From XOS
Sulfur Analysis
Method and Compliance
SINDIE® analyzers are compliant
with ASTM Standard D-7039 and are widely recognized as the preferred method
for measuring sulfur concentration in liquid hydrocarbon samples and streams.

SINDIE 7039 complies with ASTM Standard
D-7039. SINDIE 7039 meets or exceeds the performance of other X-ray
fluorescence-based ISO and ASTM test methods including ISO 20884, for the
measurement of sulfur in refinery fuels.
MWD XRF Technology
Monochromatic Wavelength
Dispersive X-Ray Fluorescence (MWD XRF) analysis provides dramatically improved
S/B over conventional XRF techniques, in a compact and simplified on-line
configuration. The improved S/B is achieved by eliminating the scattering of
bremsstrahlung from the x-ray source. The configuration of a MWD XRF unit
is shown in Figure 1. It consists of an x-ray source, a point-focusing optic for
excitation, a sample cell, a focusing optic for collection and an 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 fuel cell. The monochromatic primary beam excites the sample
and secondary characteristic fluorescence x-rays are emitted. The second
collection optic collects only the characteristic sulfur x-rays which are then
focused onto the detector.
