摘要
运用自动热脱附仪和气相色谱/质谱联用技术,通过对木制品中释放的多种挥发性有机物(VOCs)进行测试,得到较优的测试处理条件。研究发现,该方法的重现性和稳定性较好;较低的采样流速,可有效的降低苯在TenaxTA吸附管中的穿透行为。
A variety of volatile organic compounds(VOCs) associated with wood-based products were determined by combining the results from auto thermal desorption(ATD) and gas chromatography/mass spectrum(GC/MS).A lower sampling flow rate should be employed to decrease the benzene penetration into the Tenax TA tube to improve the accuracy.The results showed good repeatability and stability when this method was used.
