Increasing the precision & consistency of your Nitrogen determinations

Exeter Analytical are today one of the world's leading producers of high purity Copper (Cu) for consistent and precise analytical determination of Nitrogen (N) content in your samples.

The quality of copper used in the reduction process employed by CHN and Nitrogen analysers is widely acknowledged to critically affect the precision of N determination.

A common manufacturing method of producing Copper, for use in analytical N determinations, is to reduce copper oxide using hydrogen. A program of ongoing Research & Development at Exeter Analytical has revealed a series of critical parameters that need to be satisfied to produce high purity Copper with the maximum porous active surface area. These include the ratio of cuprous to cupric oxide, the mix of gases used in the reduction process, gas flow levels, exact manufacturing temperatures and the purification steps after the Copper has been produced. Offering consistently high active surface area, Copper from Exeter Analytical has been proven to both improve precision in N determination and also lengthen working life compared to material sourced from other sources.

Having identified the critical manufacturing parameters, Exeter Analytical investment in fully automating the process has ensured batch to batch consistency and enabled its high quality Copper to be available at competitive prices. All Exeter Analytical high quality Copper is packed under Argon to ensure long shelf life. Copper is available in quantities from single bottle to OEM quantities.
