- CHN analyzer
A CHN Analyzer is a scientific instrument which can determine the elemental composition of a sample. The name derives from the three primary elements measured by the device:
carbon(C), hydrogen(H) and nitrogen(N). Sulfur(S) and oxygen(O) can also be measured.
The analyzer uses a
combustionprocess to break down substances into simple compounds which are then measured.
By separating out inorganic carbon using a solvent, organic carbon in a sample can be measured using this device as well.
