CHN analyzer

As the name implies, a CHN Analyzer is a scientific instrument which can determine the carbon (C), hydrogen (H), and nitrogen (N) elemental concentrations in a given sample. Most CHN systems also have the capability to measure Sulfur (S) and oxygen (O). Such analyzers usually use very small quantities, many times around 1 to 3 mg of the sample. Updated CHN systems can now use upwards of 1 g of material if need be.
