研究塑料绝缘物质的热解过程对预防火灾是很有用的。面临着全世界火灾损失总数的不断增长,就需要合适的研究方法。 R. M. Lum在匹兹堡分析化学和应用光谱学会议上提出了一种以激光热解和光谱学相结合为基础的方法。聚焦激光脉冲局部加热的试样的分解产物,经过中间的缓冲室减压后,直接进入质谱仪的分祈室。一只旋转的断续光阑按一定周 Studying the pyrolysis of plastic insulation materials is very useful in preventing fires. Faced with the ever-increasing total number of fire losses worldwide, appropriate research methods are needed. R. M. Lum presented a method based on a combination of laser pyrolysis and spectroscopy at the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. Focused laser pulses locally heated sample decomposition products, after the middle of the buffer chamber decompression, directly into the spectrometer’s sub-chamber.
