ELTRA‘s CHS-580A

 

ELTRA‘s CHS-580A is the ideal analyser for the simultaneous determination of carbon, hydrogen and sulphur in organic samples.

ELTRA’s 580A analysers (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 analyser and features a vertical resistance furnace with 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 inhomogeneous materials can be reliably analysed. The analyser can be equipped with up to three independent infrared cells according to the user’s requirements, allowing for a great variety of applications.

APPLICATION EXAMPLES
  • Simultaneous carbon, sulphur and hydrogen determination with minimal sample preparation
  • wide range of organic materials can be analysed
  • 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 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, export of results)
  • single and multipoint calibration
  • low maintenance
  • robust design allows usage in production control and laboratory

FUNCTION PRINCIPLE

Operation CHS-580A

In the CHS-580A the samples are weighed into crucibles. Then a gripper places the samples from the Autoloader on the pedestal. The samples are loaded consecutively into the furnace for combustion. The average analysis time is 60 to 180 seconds. Detector signals and instrument parameters are displayed during analysis. Evaluation of the signals and display of the results are done automatically; the data can be transferred to a laboratory information management system (LIMS). The analysers require minimum maintenance. The particle filters and chemicals which need to be maintained are easily accessible.

Measuring Principle CHS-580A

In the CHS-580A analyser the sample is burnt in an oxygen atmosphere at temperatures of up to 1,550 °C. The furnace temperature can be freely selected in steps of 1 °C. The combustion gasses (CO2, H2O, SO2) coming from the furnace first pass through a dust filter and then into the heated H2O infrared cell. After the water vapor is chemically absorbed, the dried CO2 and SO2 gas is detected in the additional infrared cells. Depending on the configuration, it is possible to combine up to four infrared cells with different sensitivities.
