This review focuses on the applications of silicone in the form of tubes or rods for sorptive extraction of organic compounds as sample preparation method in combination with various chromatographic techniques. Silicone rods (SRs) and silicone tubes (STs) have the advantage of being inexpensive, flexible and robust. SRs and STs with different sizes and volumes of silicone (8-635microL) have so far been applied for the extraction/preconcentration of a large variety of organic micropollutants from different matrices. The theoretical principle of SR and ST extraction in comparison with similar microextraction techniques is presented as well as a summary of the published applications of SR and ST extraction in combination with gas chromatography (GC) or liquid chromatography (LC). Furthermore, the use of SRs and STs for time-integrated (passive) sampling is reported.
本综述重点介绍了以管或棒形式存在的硅橡胶在作为样品前处理方法与各种色谱技术联用，吸附萃取有机化合物方面的应用。硅橡胶管（SRs）和硅橡胶棒（STs）具有成本低、灵活和坚固耐用的优点。不同大小和体积的硅橡胶（8-635μL）的 SRs 和 STs 已被用于从不同基质中萃取/预浓缩各种有机微量污染物。本文还介绍了 SR 和 ST 萃取与类似微萃取技术的理论原理，并对与 GC 或 LC 联用的 SR 和 ST 萃取的已发表应用进行了总结。此外，还报告了 SRs 和 STs 在时间积分（被动）采样中的应用。
