Abstract
The trace organic oxygen analyzer has been developed for the determination of oxygen in highly volatile liquid samples such as coal-derived naphtha. Oxygen in the sample was finally converted to methane by pyrolysis over platinum carbon, followed by methanation reaction, and methane formed was measured by FID. The FID intensity was proportional to the oxygen concentration of 0.05wt% or above for o-cresol/hexane solution and the FID sensitivity was more than 100 times higher than TCD one. The structure of the analyzer is simple and its operation and maintenance are easy.
