| 摘要 |
N-nitrosamines in samples containing other nitrogen compounds may be selectively and quantitatively detected by use of a method and apparatus which provides for the quantitative detection of N-nitrosamines by gas chromatography, the pyrolysis of the qualitatively determined N-nitrosamines in a gold or platinum reaction environment at temperatures ranging from 500 DEG to 700 DEG C. and the quantitative determination of ammonia produced by the pyrolysis reaction by electrolytic conductivity detection.
