A novel analytical pyrolysis device suitable for the measurements of the less volatile pyrolyzates was developed. This device is comprised of a pyrolysis unit and a movable pyrolysis tube made of stainless steel. The upper side of the pyrolysis tube is first set at the heated center of the pyrolysis unit. A polymer sample in a sample cup is introduced into the heated center and pyrolyzed under the flow of nitrogen carrier gas. The pyrolyzates are then transferred to the bottom side of the pyrolysis tube which is cooled down by air blow and the less volatile pyrolyzates are condensed. After that the pyrolysis tube is moved down out of the pyrolysis unit by moving the three port valve. Finally the trapped pyrolyzaets was flushed by an appropriate solvent into a collection vial, which was on-line connected to the injection port of a high performance liquid chromatographic system. The performance of the system was tested by using some polymer samples forming less volatile pyrolyzates.

开发了一种适用于低挥发性热解物分析的新型热解装置。该装置由热解单元和不锈钢制成的可移动热解管组成。首先将热解管的上侧设置在热解单元的加热中心。将样品杯中的聚合物样品引入加热的中心，并在氮气载气流下热解。然后将热解物转移到热解管的底侧，热解管通过鼓风冷却，并且使挥发性较低的热解物冷凝。之后，通过移动三通阀将热解管向下移出热解单元。最后，用适当的溶剂将捕获的热解物冲洗到收集瓶中，该收集瓶在线连接到高效液相色谱系统的进样口。该系统的性能进行了测试，通过使用一些聚合物样品形成挥发性较低的热解物。
