Optimal Low Sulphur Analysis with the S8 TIGER ECO - Affordable WDXRF without Compromise on Performance

The S8 TIGER ECO “Petro” for ASTM D 2622 is the optimal solution for performing analysis of sulphur in hydrocarbon matrices such as gasoline, kerosene, diesel and mineral oil. Traces of sulphur can be analysed at ultra low detection limits and optimal precision due to the compact beam path: High sensitivity for sulphur is achieved with the close coupling between X-ray tube and sample. The germanium analyser crystal ensures optimal analytical sensitivity and resolution. The measurement of peak and background positions in sequential mode ensures that for each matrix the accurate net intensity is determined.

The S8 TIGER ECO “Petro” for ASTM D 2622 is optimised for highest instrument uptime, lowest cost of ownership and ultimate reliability. The unique vacuum seal of the S8 TIGER ECO “Petro” outperforms other conventional WDXRF due to its complete protection of the goniometer and its parts. It locks out fumes from diesel and gasoline which otherwise will enter the spectrometer chamber damaging crystals, motors and detectors. In addition it significantly reduces the helium consumption and therefore the cost of operation, because helium flushing is only required for the small sample chamber, while the goniometer remains always in vacuum. Without the need for an additional external cooling device and no need of compressed air the quick installation and reliable operation is guaranteed for the S8 TIGER ECO “Petro”.

The calibration of low sulphur in mineral oil according to ASTM D 2622-10 was performed with seven standard samples prepared by using commercially available standards covering a concentration range from 0 – 100 ppm for the low range. The high precision of the S8 TIGER ECO is shown in Table 1.

The analysis of ultra low sulphur concentrations in petroleum products according to ASTM D 2622-10 with the S8 TIGER ECO “Petro” is reliable, precise and accurate. The optimised excitation and the intensity optimised beam path with the germanium crystal leads to an unmatched analytical performance. The determination of ultra low sulphur concentrations allows driving the production of low sulphur automotive fuels with the S8 TIGER ECO in the most efficient way. It ensures that the actual and future limit values of sulphur in fuels are not exceeded along the supply chain. Due to the unique vacuum seal and the SampleCare^TM packages the S8 TIGER ECO “Petro” is an indispensible tool for every refinery and testing lab providing safe and reliable analysis of liquid fuel samples, highest instrument uptime and lowest cost of ownership. With 5 years warranty on the X-ray tube peace of mind is guaranteed.
