| 摘 要： | 用毛细管气相色谱法对一些汽油样品组分进行了分离 .在得到的色谱图上 ,选取合适的色谱峰对 ,用峰高比或峰面积比求出色谱峰对的斜率参数 ,采用极坐标法对这些参数作图 ,便得到该油品的特征指纹色谱图 ,即星状图 .将绘制好的西安市面上随机购买的几种未知汽油星状图进行对比 ,成功地确定了其油品来源 .利用星状图法对一些模拟汽油火灾的液体残留物进行了物证鉴定 ,发现其星状图和未燃原油品的星状图十分吻合 ,结果满意

| Abstract: | A method of determining the source of gasoline by using its star shaped graph is established. On the chromatograph chart of the gasoline, the pairs of proper adjacent fingerprint peaks are selected and the slopes of the straight lines of linking the peak pairs are obtained. Drawing the peak height ratio or peak area ratio and the corresponding slope of each peak pair in radial coordinates can obtain the star shaped graph. Comparing the star shaped graph of unknown gasoline with those of known commercial gasolines can determine where the gasoline is from. This method can be used for identifying some residual materials in the fire hazards causing by gasoline, and some examples show that the results of this method are very reliable. |
