补充资料:激光热解气相色谱法
分子式:
CAS号:

性质:用激光裂解器(1aser pyrolyzer)作为进样器的气相色谱法。在激光照射下,试样温度升高而裂解,产物被载气带入色谱仪进行分离检测。这种裂解装置升温速度快,裂解温度高,次级反应少,死体积小,得到的裂解谱图比较简单。但这种装置的结构较复杂,裂解温度难以控制和测定,且与样品颜色有关,操作也比较复杂。裂解色谱目前应用最广的是高聚物分析,在一定的裂解色谱条件下,不同的高聚物可得到各自的指纹图,用于鉴别各种高聚物。还可测定共聚组成;区分共混物和共聚物;测定某些高聚物端基,从而确定聚合物分子量;测定某些高聚物链结构及对高聚物的热稳定性、耐老化性、加工过程等多种性能进行研究。此外,还可用于医学、生物学等各领域。
