Energy dispersive X-ray fluorescent analyzer EDXRF of sulfur in petroleum and petroleum products.
“SPECTROSCAN S“ variant SL energy dispersive X-ray fluorescent EDXRF analyzer of sulfur in petroleum and petroleum products is used for determination of sulfur weight content in petroleum and petroleum products such as diesel fuel, gasoline, kerosene, lubrication oil, crude oil, hydraulic oil, etc. at refinery factories, in research laboratories of oil Industry, oil-transport companies, as well as in mobile laboratories meeting requirements of:
ASTM D4294 Standard Test Method for Sulfur in Petroleum and Petroleum Products by Energy Dispersive X-ray Fluorescence Spectrometry (EDXRF);
ISO 20847:2004 Petroleum products -- Determination of sulfur content of automotive fuels -- Energy-dispersive X-ray fluorescence spectrometry (EDXRF).
Routine work with the Analyzer does not require high skills of the staff and can be fulfilled by a laboratory assistant with no control from analysts.
"SPECTROSCAN S" variant SL is a desk top with inbuilt computer and printer.
Due to lateral position of the sample additional errors due to contamination of the additional protection film are excluded therefore unique analytical parameters are achieved for EDX instruments of this type.
