Exeter Analytical CE 440 Elemental Analyzer

Exeter image The Exeter Analytical model CE 440 elemental analyzer provides automated analysis of particulate carbon, hydrogen, nitrogen and sulfur following the general methodology outlined by Gordon (1969) and Sharp (1974). The Model CE-440 uses thermal conductivity detection to measure carbon, hydrogen and nitrogen, after combusting and reducing a sample. Inherently more stable than gas chromatographic based systems, the Model CE-440 delivers superior performance and sampling precision over the wide range of sample types. In addition to the more conventional (for oceanographic purposes) measurements of CHN, the S-LAB offers elemental sulfur analysis as well, as this is a critically important element to quantify in many sediment biogeochemical studies
