Abstract

Sample preparation is a crucial aspect of analytical methods, particularly when dealing with complex matrices and/or low concentrations of analytes. Recent advancements in analytical methods have focused on minimizing sample preparation devices, evolving towards extraction techniques that utilize solvent-free or green solvents, or minimal amounts of solvents. Microextraction by Packed Sorbent (MEPS) is a miniaturized version of the conventional Solid-phase extraction (SPE) technique. The MEPS has been recognized as a modern technique in sample preparation due to the minimal use of solid adsorbent, organic solvent, and liquid sample. This innovative technique allows for the recovery of the adsorbents and contributes to sustainability. Furthermore, MEPS can be seamlessly integrated with chromatographic systems in an automated manner to enhance both efficiency and reproducibility. This review tries to have comprehensive insight into the various MEPS technique, advancements, and emerging trends with emphasis on the wide range of employed nanomaterials as adsorbents.

填料吸附剂微萃取（MEPS）：基本原理和基于纳米材料的吸附剂

样品制备是分析方法的一个关键环节，尤其是在处理复杂基质和/或低浓度分析物时。分析方法的最新进展主要集中在最大限度地减少样品制备设备上，并朝着使用无溶剂或绿色溶剂或最少溶剂的萃取技术方向发展。填料吸附微萃取（MEPS）是传统固相萃取（SPE）技术的微型化版本。由于只需使用极少量的固体吸附剂、有机溶剂和液体样品，MEPS 已被公认为是一种现代化的样品制备技术。这种创新技术可以回收吸附剂，有助于实现可持续发展。此外，MEPS 还可与色谱系统无缝自动集成，以提高效率和可重复性。本综述试图全面介绍各种 MEPS 技术、进展和新兴趋势，重点是广泛使用的纳米材料作为吸附剂。
