利用超音速分子束同步測定分光法對芳香族化合物的分析

Synchronous Scan Luminescence Techniques in Supersonic Jet Spectrometry Applied to Polycyclic Aromatic Hydrocarbons

摘要


利用超音速分子束分光法與同步測定法的結合,可以對芳香族化合物做一個高解析度與高靈敏度的分析。這方法是利用雷射的激發波長與分光器的觀測波長一致而同時掃描,一般的情形之下,一個峰對應一個化合物,如同氣相層析術。其分解度約2.5 X 10^4。這方法也應用在液化炭的分析,其中蔥的含量約100 ppm。

並列摘要


Supersonic jet spectrometry is combined with Synchronous scan luminescence spectrometry. The fluorescence wavelength is synchronously scanned with the excitation wavelength. When the wavelength difference is adjusted to 0 nm, a single component gives a single peak in most cases, like chromatography. The resolving power, the ratio of the dynamic range and the line width, is 2.5 X 10^4. The method is applied to a real sample. The content of anthracene in solvent-refined coal was calculated to be 100 ppm.
