Solid phase extraction (SPE) is a popular sample preparation technique, which can be applied directly in gas-solid phase and liquid-solid phase, or indirectly to solid samples by using, e.g., thermodesorption with subsequent chromatographic analysis. Although SPE can be described as a physical extraction process involving a liquid phase and a solid phase, the increased use of packed sorbent formats seems to have led to a bias toward packed sorbent SPE devices. Without any doubt, the heart of the SPE technique is the sorbent material as it has a direct influence on the selectivity, sorptive capacity, and the format or the configuration of the resultant SPE device. There will always be a need for new sorbent materials, and therefore, it is imperative to focus research efforts on versatile sorbent fabrication techniques that could address current and anticipated challenges. Various polymeric materials have been developed and implemented in everyday life. They are also extensively used in analytical chemistry. This review provides an updated summary of the most important features of polymeric sorptive materials used at the stage of preparing samples for analysis. The application of each new polymeric sorbent material is discussed in detail. Moreover, the comparison between these materials is done.
固相萃取 (SPE) 是一种流行的样品制备技术，可直接应用于气固相和液固相，或通过例如热解吸随后进行色谱分析间接应用于固相。尽管 SPE 可以描述为涉及液相和固相的物理萃取过程，但填充吸附剂格式的广泛使用似乎导致了对填充吸附剂 SPE 设备的偏见。毫无疑问，SPE 技术的核心是吸附剂材料，因为它直接影响选择性、吸附能力以及所得 SPE 设备的格式或配置。将始终需要新的吸附剂材料，因此，必须将研究重点放在多功能吸附剂制造技术上，以应对当前和预期的挑战。各种聚合物材料已经开发并应用于日常生活中。它们也广泛用于分析化学。本综述提供了用于分析前样品制备阶段的聚合物吸附材料的最重要特征的最新总结。详细讨论了每种新型聚合物吸附材料的应用。此外，还对这些材料进行了比较。
