CHNS (O) Analyzer

     Kindly download Material Safety Data sheet and submit the hardcopy of filled sheet along with your sample

  Instrument Details  

Make : ThermoFisher Scientific
Model : Flash smart V CHNS/O
Specification : Estimation of CHN/CHNS/O in percentage   level to high concentration level.

         The CHNS(O) Analyzer find utility in determining the percentages of Carbon, Hydrogen, Nitrogen, Sulphur and Oxygen of organic compounds, based on the principle of "Dumas method" which involves the complete and instantaneous oxidation of the sample by "flash combustion". The combustion products are separated by a chromatographic column and detected by the thermal conductivity detector (T.C.D.), which gives an output signal proportional to the concentration of the individual components of the mixture.






  Working Principles   

         There are different techniques for the determination of CHN\CHNS\O. It brings a new level of precision, accuracy, speed of analysis and ease of operation.The built in chromatographic column converts the compound and elutes it in the form of NO2,CO2, SO2,H2O which are then detected with the help of Thermal Conductivity Detector.



         The instrument is calibrated with the analysis of std compounds using the K-factors calculations. Thus the instrument ensures maximum reliability of the results because the combustion gases are not split or diluted but directly carried to build in GC system simultaneous determination of CHNS can be done in less than 10 mins. This method finds greatest utility in finding out percentages of C, H, N, S, (O) in organic compounds which are generally combustible at 1800o C.
         Key components of CHNS are auto sampler, combustion reactors ,chromatographic column, and T.C.D. detector.
