Eltra Analyzer CHS-580A | Carbon / Sulfur / Hydrogen

ELTRA‘s CHS-580A is the ideal analyzer for the simultaneous determination of carbon, hydrogen, and sulfur in organic samples. ELTRA's 580A analyzers (A = Autoloader) are equipped with an automatic sample loader, allowing for analysis of large numbers of samples without operator intervention.

The sample loader is available in two versions to accommodate 36 or 130 crucibles. The CHS-580A is based on the technology of the CHS-580 analyzer and features a vertical resistance furnace with a ceramic tube. The temperature can be set in steps of 1 °C to a maximum of 1,550 °C.

Thanks to sample weights of up to 500 mg and more even in-homogeneous materials can be reliably analyzed. The analyzer can be equipped with up to three independent infrared cells according to the user's requirements, allowing for a great variety of applications.


  • Simultaneous carbon, sulfur, and hydrogen determination with minimal sample preparation
  • A wide range of organic materials can be analyzed
  • Rapid, precise, accurate, and reliable element determination
  • Resistance furnace can be set up to 1550 °c in steps of 1 °c
  • Customized infrared cells provide a wide, dynamic measuring range
  • Due to gold ir path, increased cell live time for analysis of halogen or acid-containing samples
  • Powerful software (multilingual, customized display, the export of results)
  • Single and multi-point calibration
  • Low maintenance
  • The robust design allows usage in production control and laboratory
