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 that the user can select between 30 and 110 °C. The ECS 4010 is a fully automated, microprocessor controlled analytical unit interfaced with a computer. The results can be viewed directly via PC using dedicated software. The ECS 4010 is suggested when big amount of sample is burnt (for example in soil, sediment analysis). The ECS 4010 is also suggested in laboratories where a lot of samples are analysed. This model is suggested for N; N,C; N,C,H; N,C,H,S analysis. Thanks to the double furnace configuration a better optimization of catalyst consumption is possible.
