ABSTRACT:
Disclosed is an improvement of quantitative analysis of oxygen content in an organic compound. The accuracy of the quantitative determination is substantially improved by adding hydrogen or methane to a carrier gas.
The carbon-reduction process is performed in the presence of hydrogen or methane in the thermal decomposition tube, thus retaining the catalyst in the state of not being contaminated with oxygen or oxygen compound by depriving the catalyst of the oxygen or oxygen compound which is released from the air and moisture undesirably entering the tube and from the thermal decomposition gas of the sample.
