The CE 440 uses a thermal conductivity detection method far measuring carbon, hydrogen, and nitrogen after combustion and reduction. This method gives rapid and highly accurate measurements over a very wide range of elemental compositions, with most measurements completed in less than 5 minutes. The CE 440 advanced Windows-based software, with data storage, statistical analisys, flexible report generation and continuous diagnostic and automatic maintenance alerts, controls and monitors all instrument functions. This simplifies operation for consistent operator-to-operator results, no matter what sample types you analyze. Plus, due to its low gas and reagent consumpion, the CE-440 offers the lowest cost per sample in the industry.
Applications
Organics and pharmaceuticals: The CE 440 can analyze virtually any claa of organics, including organometallics, heterocyclic nitrogen derivatives, steroids, polynuclear aromatics and organophosphorous.
Environmental: Determine the presence of fuels, oils, and their by-products in the environment, or study the composition of material retained by membranes used in oceanographic research, water filtration and air monitoring.
Polymers: The Ce 440 provides a fast, direct method for determining elemental composition of polymers, copolymers, and blends. Even samples with high levels of halogens, like PCV or Teflon, can be analyzed rapidly and accurately.
Refractories: Nitrides, graphite fibers, and ceramics can be analyzed- even carbides with melting points over 2000oC
Volatile/ Air sensitive samples: Volatile and air sensitive materials are easily analyzed with the aid of our capsule sealing device.
Other application areas: Plastics, petrochemicals, agriculture, food, and pyrotechnocal compounds.
