DESCRIPTION

SPECTROSCAN SW-D3 is a wavelength dispersive X-ray fluorescence WDXRF analyzer of sulfur in petroleum and petroleum products is used for determination of low sulfur weight content in automobile fuel, 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 EN ISO 20884, ASTM D2622, ASTM D6334.

SPECTROSCAN SW-D3 is a desk top with inbuilt computer and printer. It consists of two blocks: Spectrometer and vacuum pump. The spectrometer has a closed cycle water cooling system. The measuring tract is in vacuum chamber, but the sample is at the ambient conditions.

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.

ADVANTAGES

Due to the original design no He blowdown is required, providing LLD of 1 ppm

  • Simple in operation;
  • Desk top instrument;
  • 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;
  • 3-position sample automatic changer makes analysis of sample replicateseasy.

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

The analyzer was developed for sulfur determination and meets requirements of
1. ISO 20884:2004 Petroleum products -- Determination of sulfur content of automotive fuels -- Wavelength-dispersive X-ray fluorescence spectrometry
