通过光学和电子显微镜对用于固相微萃取 (SPME) 的市售聚二甲基硅氧烷 (PDMS) 和 Carboxen-PDMS 纤维的表面进行了研究，观察到了涂层的损坏以及新纤维的污染以及 Carboxen-PDMS 涂层中的孔数量变化很大，再加上纤维在使用过程中受到来自 SPME 纤维支架的金属颗粒的污染，这些可能解释了有机铅、有机锡和有机铅分析中遇到的问题。有机硫化合物，例如伪影形成和低重复性。
The surfaces of commercially available polydimethylsiloxane (PDMS) and Carboxen-PDMS fibers for solid-phase microextraction (SPME) were investigated by optical and electron microscopy, Damage to the coating as well as contamination of new fibers and a highly variable number of pores in Carboxen-PDMS coatings were observed, Together with the contamination of the fibers during their use with metallic particles originating from the SPME fiber holder they are possible explanations for the problems encountered in the analysis of organolead, organotin and organosulfur compounds, such as artifact formation and low repeatability.
