The ECS 4024 elemental analyzer is an instrument for organic elemental analysis based on high temperature catalytic combustion (Dumas method) for the simultaneous determination of CHNS elements and optionally O.
ECS 4024 is a semi-automatic analytical unit, controlled by a microprocessor and interfaced to a PC. The results can be displayed directly via PC using dedicated software.
It is a highly sensitive analysis instrument, very flexible and combines robustness and reliability to meet the most diverse analytical needs; it is possible, in fact, to connect it to other units for the determination of the isotopic ratios of stable elements.
The ECS 4024 is suitable for so-called “micro weighing”, i.e. for the analysis of particularly homogeneous samples, which do not require a significant quantity of sample to obtain excellent repeatability.

The ECS 4024 is the semi-automatic model that represents an evolution of the elemental analysis techniques based on “flash combustion” and chromatographic separation. The combustion gases CO2, H2O, SO2 and N2 are separated in a GC column maintained at a constant temperature, selectable by the user between 30° and 110 °C. The detection and determination of the concentrations of the various elements is carried out by a thermal conductivity detector (TCD).
