"Thermal desorption experiments" were carried out during which heavy metal evaporation was studied by on-line monitoring. This could be achieved by the use of a tubular furnace connected to a heavy metal detector, i.e. an ICP-OES (inductively coupled plasma optical emission spectrometer), by a specially designed and patented interface. The spectrograms typically had a time resolution of four different elements per minute using a conventional (sequentially operating) ICP-OES. This study shows how thermo-desorption spectrometry (TDS) can be applied to study the evaporation of high boiling substances, such as heavy metal and alkali metal compounds. The future scope of the method is discussed.
进行了“热脱附实验”,在此期间通过在线监测研究重金属蒸发情况。这可以通过使用连接到重金属探测器(即电感耦合等离子体发射光谱仪ICP - OES)的管式炉来实现,该管式炉通过一个专门设计并获得专利的接口与探测器相连。使用传统的(顺序操作的)ICP - OES时,光谱图通常具有每分钟分辨四种不同元素的时间分辨率。本研究展示了热脱附光谱法(TDS)如何应用于研究高沸点物质(如重金属和碱金属化合物)的蒸发情况。文中还讨论了该方法未来的应用范围。
