随着高分子工业的发展,高分子材料的品种不断增多,并已广泛地应用在日常生活中。近十多年来,人们在树脂中添加或共聚少量第二或第三组分来改性或控制高分子的序列结构,使高分子材料具有更优良的性能和用途。这类产品即使在专门化的实验室里,用红外、核磁共振等物理方法直接检定也有一定的困难,往往要借助于快速、灵敏、高分离的裂解气相色谱。在一般的气相色谱仪前面安装一只裂解器,即可进行裂解气相色谱工作,因而价廉、简便;样品不必特殊处理;鉴定结果可靠,与红外等方法鉴定结果一致;对样品的适应性好、特异性强、灵敏度高等优点又是其它一些物理方法所不及的。实为工厂自行鉴定高
With the development of the polymer industry, the varieties of polymer materials continue to increase, and has been widely used in daily life. In the recent ten years, people added or copolymerized a small amount of second or third component in the resin to modify or control the sequence structure of the polymer, which made the polymer material have better performance and use. Such products even in specialized laboratories, physical methods such as infrared, nuclear magnetic resonance and other direct test also have some difficulties, often with the help of fast, sensitive, high-resolution pyrolysis gas chromatography. In the general gas chromatograph installed in front of a cracker, you can crack pyrolysis gas chromatography work, so cheap, simple; sample without special treatment; identification of reliable results, and infrared methods such as the identification of the same; good adaptability of the sample , Specificity, high sensitivity and some other physical methods is beyond the reach of the advantages. In fact, the factory self-identification high
