This method is used for organic samples that cannot be analysed by ESI-MS.

The percentage of carbon, hydrogen, nitrogen (and sulfur) are determined by combustion of the material followed by gaschromatography of the produced gases.

At least 5-6 mg of material are needed for an analysis in triplicate.

Standard method is CHN

CHNS only on request and for non-fluorinated compounds! Minimum sample number of 10.
