CHNS-O ELEMENTAL COMBUSTION SYSTEM
The elemental analyzer CHNS-O Classic 4024 Model is an instrument for organic elemental analysis based on the Dumas method for the simultaneous determination of CHNS-O elements.
It represents an evolution of the elemental analysis techniques based on “flash combustion” / chromatographic separation. CO2, H2O, SO2 and N2 are separated in a GC column kept at a constant temperature, user selectable within 30 deg up to 110 deg C range.
The ECS Classic 4024 is a fully automated, microprocessor controlled analytical unit interfaced to a PC. The results can be viewed directly via PC using a dedicated software.
