Submit request

SPECTROSCAN SW-D3 is a reliable and accurate WDXRF analyzer of sulfur in liquids. It provides quick determination of sulfur weight content with Limit of Detection as low as 0.15 ppm.


SPECTROSCAN SW-D3 fully complies with international standards for sulfur analysis by WDXRF technique. Advanced design, intuitive menu and extended set of CRMs and consumables in starter pack makes easy the work even for a non-professional analyst.

"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.

Due to the original design no He blowdown is required, providing LOD as low as 0.15 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 samples;
  • 3-position sample automatic changer makes analysis of sample replicateseasy.
Due to lateral position of the sample:
  • Error due to water and air bulbs are excluded;
  • Contamination 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.

SPECTROSCAN SW-D3 provides determination of sulfur weight content in all types of liquids with Limit of Detection as low as 0.15 ppm.

SPECTROSCAN SW-D3 fully complies with international standards for sulfur analysis by WDXRF technique.
