thermal desorption method

The method of thermal desorption

热解吸方法

The targets of this method is benzene, toluene, xylene ( three isomeric), styrene. It sampling on carbon tube, solvent desorbed or indirect thermal desorption and acked column gas chromatography to determination of aromatic hydrocarbon.

该方法主要检测的目标化合物包括苯、甲苯、二甲苯（三种异构体）、苯乙烯，采用活性炭采样，并使用二硫化碳溶剂解吸或间接热解吸的方法，配合填充柱气相色谱法分析。

Therefore, it was an effective analysis method for trace volatile organic compounds in samples with the proposed method which extraction with Fe/ SiO2/ PDMS particles and then thermal desorption with electromagnetic induction heating, subsequently detection with related combined technology.

因此对于样品中痕量易挥发的有机物，使用Fe/SiO2/PDMS颗粒进行富集，并利用电磁感应加热进行热解吸，随后与相关分析技术联用进行分析检测将是一种行之有效的分析方法。

Taking account of the economic and safety factors of various treatment techniques, it has been recommended that the dioxin contaminated soil would be treated by the indirect thermal desorption method.
