| Research Abstract |
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.
