采用GC-9A型气相色谱仪,配以居里点裂解器,考查了色谱柱的温度和裂解时间等因素 后,选择了较理想的色谱分离条件和裂解条件,利用此条件对常见的橡胶种类以及同种类的 橡胶制品(汽车轮胎胶和橡皮)进行了分析,达到了种类认定以及厂家、产地、牌号的认 定。此方法样品用量少,操作简便,分析速度快,分辨率高,在法庭实验室具有实用价值。 GC-9A gas chromatography coupled with Curie point cracker, the column temperature and cracking time and other factors were investigated, the more ideal conditions for the chromatographic separation and cleavage were selected, the use of this condition on the common rubber species And the same type of rubber products (car tire rubber and rubber) were analyzed to achieve the type of identification and manufacturers, origin, grade recognition. This method has the advantages of less dosage, simple operation, fast analysis, high resolution and practical value in forensic laboratories.
