Sažetak
The method for direct oxygen analysis as described by
Schutze, Zimmerman and Unterzaucher has been modified. The
Korbl catalyst was employed to remove some interfering gases and
to oxidize carbon monoxide to carbon dioxide. The described
method has been successful for the determination of oxygen in
compounds which, in addition to carbon, hydrogen and oxygen
contain nitrogen, halogens or sulphur.
With various types of organic samples the determinations
showed a standard deviation of 0.130/o. The time required for the
analysis is thirty minutes if a series of analyses is being made in
succession. The oxidation tube needs repacking after 150-200
analyses.
