Description

DESCRIPTION
Energy dispersive X-ray FLUORECENCE analyzer EDXRF of low sulfur 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.

ANALYTICAL PARAMETERS
“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.

Analytical parameters

S (sulfur)

Limit of detection  for100 s
5 ppm

Sulfur concentration range for determination
Two ranges:

– from 0,0007% to 0,10% (from 7ppm to 1000 ppm);

– from  0,1% to 5% (from 1000 ppm to 50000 ppm);

Sample cups, diameter, volume

∅32 mm, V 8 cm3

∅32 mm, V 8 cm3, ventilated

X-ray tube capacity
less 1.0 W

Interface
Inbuilt display and thermoprinter

Dimensions and weight (not more)
360х380х180 mm, 8,5 kg

Power supply
220 V, ~ 50 Hz, 100 W

ADVANTAGES
Due to the original design no He blowdown is required, providing LLD of 7 ppm

Simple in operation, now installation required;
Analyzer parameters are suitable for mobile laboratories; 
The sample data and analysis results are shown in display and printed out by inbuilt printer;
Special ventilated cups are developed for volatile petroleum products.

Due to lateral position of the sample:

Error due to water and air bulbs in petroleum products are excluded;
Contamination with petroleum products of the inner parts of the analyzer is excluded;
Additional errors due to contamination of the additional protection film is excluded; 
Sample loading unit is easily cleaned.

Minimum operator actions:

Put in the number or name of the sample from inbuilt key-board;
Fill in two sample cups with the sample;
Put in the samples into the analyzer and start measurements.

All the rest operations are run automatically.

APPLICATIONS
“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, jet fuel and any petroleum distillate.
The Analyzer may be used for petroleum products quality examination at refinery, research laboratories, petroleum transport and mobile laboratories.
The range of the Analyzer applications is determined with various standards, such as:
ASTM D4294-16 Standard Test Method for Sulfur in Petroleum and Petroleum Products by Energy Dispersive X-ray Fluorescence Spectrometry
ISO 20847:2004 Petroleum products — Determination of sulfur content of automotive fuels — Energy-dispersive X-ray fluorescence spectrometry.
