Wavelength dispersive X-Ray fluorescence analyzer for sulfur and chlorine in liquids quantification.
Submit request

SPECTROSCAN CLSW is a reliable and accurate WDXRF analyzer of sulfur and chlorine in liquids. It provides quick determination of sulfur and chlorine weight content with Limit of Detection as low as 0.3 ppm for sulfur and 0.2 ppm for chlorine.

SPECTROSCAN CLSW fully complies with international standards for sulfur and chlorine 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.

Due to the original design no He blowdown is required, providing LOD as low as 0.2 ppm for CI and 0.3 ppm for S
  • 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 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:
  • Sample preparation;
  • 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 CLSW provides determination of chlorine and sulfur weight content in all types of liquids with Limits of Detection as low as 0.2 ppm for chlorine and 0.3 ppm for sulfur.

SPECTROSCAN CLSW fully complies with international standards for chlorine and sulfur analysis by WDXRF technique.
