Sindie Bio Bench-Top
The Sindie Bio analyzer provides the ultimate plug-it-in and measure bench-top sulfur measurement solution for bio fuels. The unit is compact and fits on any lab bench . This Monochromatic WD XRF analyzer, per ASTM D7039, quantifies sulfur concentration from 0.4 ppm up to 3000 ppm. Monochromatic WD XRF is a direct measurement technique which does not require sample conversion, consumable gases, or high temperature operating conditions.
The Sindie technique employs a low-power X-ray tube, a point-focusing doubly-curved crystal (DCC) optic for excitation, a sample cell, a second focusing DCC optic for collection, and an X-ray detector. The first point focusing optic captures a narrow bandwidth of X-rays from the source and focuses this intense monochromatic beam to a small spot on the fuel sample cell. The monochromatic beam excites the sample and secondary characteristic fluorescence X-rays are emitted. The second collection optic collects only the characteristic sulfur X-rays emitted from the small spot sample and focuses them onto the detector. This configuration offers several advantages over conventional WDXRF systems. The signal-to-background is improved by using the monochromatic excitation of the X-ray source characteristic line. The focusing ability of the collection optic allows using a small-area X-ray counter detector which results in low detector noise and enhanced reliability. This technique enables robust low-maintenance analyzers with dramatically lower detection limits and faster response times.
The main features of the Sindie Bio bench-top analyzer include:
- Direct measurement without sample conversion; Analysis in ppm (wt)
- LOD : 0.4 ppm
- Dynamic Range: 0.4 ppm to 3000 ppm
