Carbon, Hydrogen and Nitrogen Analysis

The carbon, hydrogen & nitrogen analyzer is used to measure carbon, hydrogen and nitrogen concentrations in various solid materials. Typically less than 0.1 grams of sample is dropped into a hot combustion tube in a stream of oxygen. The sample burns, forming carbon dioxide, water vapor and nitrogen oxides which are detected and measured by the unit.

Typical methods include

ASTM method D 3176
