Simultaneous Determination Of Carbon Research Articles

Submilligram determination of carbon, hydrogen, and nitrogen

The procedure described byFrazer4,6 for the simultaneous determination of carbon, hydrogen, and nitrogen has been scaled down to the submilligram level with no serious loss of accuracy. Approximately six complete determinations can be made in an eight-hour day. Whereas the accuracy depends to a large extent upon the analyst's technique, the method presented is comparatively straightforward. Analysts with no previous microanalytical training have been able to obtain results equivalent to the accuracy shown in Table I after two weeks of experience with the procedure.

Simultaneous determination of carbon, hydrogen, and nitrogen. Part II

An analytical procedure is described which allows the simultaneous determination of carbon, hydrogen, and nitrogen in solid organic materials by gas-volumetric techniques. The accuracy is comparable to that obtained with the more conventional methods.

Simultaneous determination of carbon hydrogen, halogen, or sulfur content by the deflagration combustion method

1. Methods have been developed to carry out the simultaneous and separate determination of carbon, hydrogen, halogen or sulfur by deflagration combustion. 2. The presence of elements in the molecule which form nonvolatile oxides during combustion does not prevent the C and H being determined. 3. The method gives good reproducible results with an error in determination which does not exceed ±0.3%.

Simultaneous determination of carbon, hydrogen, and halogens

It was shown that carbon, hydrogen, and nitrogen can be determined simultaneously by the pyrolytic decomposition of the organic substance in a stream of oxygen in an empty combustion tube. Carbon and hydrogen are determined in the usual way, and nitrogen is determined from the sum of the amounts present as nitrogen oxides and as elementary nitrogen.
