The Model 440 CHN analyzer from Exeter Analytical Inc. has become the system of choice for many Contract Research Organizations and Service Labs because of its proven ability to accurately analyze the widest range of sample types - quickly, easily and reliably.
Operating across a wide linear range, the Model 440 is capable of routinely determining percentage Carbon, Hydrogen and Nitrogen levels in almost any sample type including organic compounds, pharmaceuticals, petrochemicals, polymers, refractory, environmental or natural materials (soil, plants or insects).
The Model 440 delivers unmatched productivity and top quality results as it benefits from a furnace design that prevents cross contamination and allows the running of a greater number of samples between combustion tube changes.
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.
Low gas and reagent consumption combined with high reduction tube life allows the Model 440 to deliver some of the lowest operating costs of any CHN elemental analyzer available. Intuitive Windows based operating software reduces human errors through incorporation of extensive automation, comprehensive customer help and diagnostic facilities. Most parts on the Model 440 are user replaceable further reducing operating costs and downtime.
