The Exeter Analytical Model 440 CHN accurately analyzes a wide range of sample types for percentage Carbon, Hydrogen and Nitrogen (CHN) - quickly, easily and reliably. Operating across a wide linear range the Model 440 is capable of routinely analyzing almost any sample type including organic compounds, pharmaceuticals, petrochemicals, polymers, refractory, environmental or natural materials (soil, plants or insects). The Model 440’s horizontal furnace design prevents cross contamination and allows for a greater number of samples between combustion tube changes as residue is routinely removed between each analysis. Based upon a unique combined static / dynamic combustion technology the Model 440 is able to precisely analyze the widest range of sample types from volatile to difficult to combust materials including nitrides, graphite fibres, ceramics and even carbides with melting points of over 2000°C. Offering unmatched operating accuracy and precision, the fully automated Model 440 delivers simultaneous CHN analysis in less than 5 minutes increasing the productivity of your laboratory.
