Solid-Phase Microextraction Combined with Flow-Modulated Comprehensive Two-Dimensional Gas Chromatography for Screening Leachables in the Pharmaceutical Industry
Nanomaterials are extremely useful as sorbents for sample preparation, because of their varied morphologies, high surface area, surface-tovolume
ratio, porosity, and ability to interact with samples in a variety of ways. Here, we review how nanomaterials are being used in a variety
of sample preparation techniques, such as dispersive solid-phase extraction (dSPE), solid-phase microextraction, stir-bar sorptive extraction, and matrix solid-phase dispersion.
