Elemental analysis of organo-metallic compounds The simultaneous determination of carbon, hydrogen and other elements in one weighed sample.
A method is described for simultaneous gravimetric microdetermination of carbon, hydrogen and one or more heteroelements in one weighed sample of organic substances. The method is based on pyrolytic combustion of the sample in a quartz container placed in an empty combustion tube. The carbon and hydrogen determination is completed as usual. Hetero-elements, in the form of volatile compounds, are retained in special previously weighed tubes inside the combustion tube. Hetero-elements forming non-volatile residues can be determined by the change in weight of the quartz sample-container. Volatile elements or compounds are determined by weighing the quartz insert tube. More than 40 elements in various combinations can be determined simultaneously with carbon and hydrogen.
