三种测定洗油萘含量气相色谱法的比较

Comparison Between Three Gas Chromatography Methods in Determining Naphthalene Content in the Wash Oil

介绍了填充柱外标法、毛细管柱归一法和毛细管柱内标法3种测定洗油萘含量的气相色谱法,根据工作经验和实验数据,阐述了其优缺点,对其在工厂生产实践的应用,提出了如下的建议:从实用性的角度考虑,归一化法是首选的定量方法;从准确性的角度考虑,内标法稍占优势;在必要时,需要采用国标规定的外标法。

Three methods in determining naphthalene content in the wash oil with gas chromatography were introduced, and the advantages and disadvantages of the three experimental methods based on their work experience and experimental data were expounded. Scientific and reasonable suggestions about the application of the three methods in production practice were put forward.
