Automatic procedure for the CHN-analysis of organic substances in the milligram range

Organic elemental analysis

“…The determination of carbon, hydrogen, and another element, especially nitrogen or the halogens, has drawn the most interest. Wachberger, Dirscherl, and Pulver (242) developed an automatic apparatus for the determination of carbon, hydrogen, and nitrogen. The sample was combusted in oxygen and the combustion products were separated in a stream of helium by means of selective adsorption and desorption.…”
