摘要

C. Gerhardt, German manufacturer of analytical equipment, offers two alternatives regarding nitrogen determination. The DUMATHERM works using the Dumas combustion method, where a sample is burned in an oxygen-rich atmosphere at high temperatures and the resulting gases are analysed by a nitrogen detector. The clever design of the furnace chamber in combination with the direct analysis of all resulting gases provides the user with results within 2-4 minutes, depending on the type of sample. Thanks to its construction, the DUMATHERM has low wear and tear on parts, which reduces costs for service significantly, and the oxygen required during a test can be up to 90% less than with other brands. The new improved version comes with an auto sampler that holds 64 samples, allowing more productivity.
