The gaschromatographic analysis methods of C5 fraction and its products were optimized by using self-made SE-30 capillary columns of different film thicknesses.
采用自制的不同膜厚SE-30毛细管色谱柱，对C5馏分及其产品的气相色谱分析条件进行优化。

It is studied to measure the efficiency of gaschromatographic packed columns with the linear relationship between peak width and retention time.
利用半峰宽与保留时间的线性关系，对气相色谱填充柱柱效能的测定作了进一步的研究。
3
A gaschromatographic method without derivatization was established for residue analysis of 10 organonitrogen pesticides in soil, water, cereals, fruit and vegetable.
