气相色谱法分析焦化轻苯的组分

用同一填充柱在程序升温条件下分离轻苯及精制苯中各组分，并用直接面积归一化法进行定量，苯组分相对误差为0．94％，是苯类产品组分含量控制分析简便、易行的实用方法。

To use same filling column to separate every components in light benzene and refined benzene under the conditions of program controlled temperature rising, and then to quantitatively determine with direct area normalization approach, demonstrating the relative errors of benzene components is 0. 94%. It is a simple, feasible and practical method to analyze and control the component contents of benzene products.
