This article reviews how nanomaterials are being used in a variety of sample preparation techniques, such as dispersive solid-phase extraction (dSPE), solid-phase microextraction (SPME), stir-bar sorptive extraction (SBSE), and matrix solid-phase dispersion (MSPD).
The analysis of contaminants found in environmental waters and originating from personal care products using metalorganic frameworks (MOFs) combined with liquid chromatography (LC) is described. This work expands the use of MOFs from gas chromatography to LC and also meets the requirements of green analytical chemistry.
A simple method for the analysis of leachables using solid-phase microextraction (SPME) and comprehensive two-dimensional gas chromatography, coupled to mass spectrometry (GCxGC–MS). This fully automated method bypasses the use of solvents and excessive sample handling. Four potential leachables were tentatively identified.
