Fabrication of novel nanoporous array anodic alumina solid-phase microextraction fiber coating and its potential application for headspace sampling of biological volatile organic compounds

Polyethylene glycol/graphene oxide coated solid‐phase microextraction fiber for analysis of phenols and phthalate esters coupled with gas chromatography

“…The fiber coating is the core of the SPME technology because the extraction efficiency of analytes mainly depends on the properties of extraction materials. So far, the studied fiber coatings have encompassed polymeric materials , carbon nanomaterials , metallic and metal oxide nanomaterials , and nanofibers , etc. Meanwhile, the composites including different organic compounds and organic–inorganic hybrid material have been also regarded as the promising adsorbing materials, which can play their particular roles to obtain higher extraction efficiency.…”

An Ag2S@ZnS‐coated fiber for efficient, long‐life solid‐phase microextraction of polycyclic aromatic hydrocarbons in water

“…And the detailed preparation process of Ag 2 S@ZnS-coated SPME fiber is described as the following. First, the preparation of aluminum chromium phosphate binder and the pretreatment of stainless steel wire substrate were carried out as described in [27]. Then, the as-prepared adsorbents were uniformly dispersed in the chromium phosphate binder with a ratio (aluminum chromium phosphate binder:adsorbent:N-methylpyrrolidone:N, N- .…”

Ordered mesoporous carbon/Nafion as a versatile and selective solid-phase microextraction coating

“…In addition, some task-specific SPME coatings such as molecularly imprinted polymers [5][6][7][8], conducting polymers [9][10][11][12], ionic liquids [13][14][15][16], sol-gel materials [17][18][19], biosorbents [20,21], and nanomaterials (NMs) [22][23][24] with enhanced extraction efficiency, selectivity, and chemical stability were developed to accomplish the extraction of a wide range of analytes in different matrixes. Among the tested SPME coatings, NMs including metal and metal oxide nanoparticles [25][26][27][28], metal-organic frameworks [29][30][31], siliceous NMs [32,33], and carbonaceous NMs (CNMs) [34] have received much attention due to their unique physicochemical properties. CNMs, as a member of NMs, have emerged as a robust alternative to commercial coatings in virtue of its remarkable electronic properties, excellent mechanical strength and thermal stability [22,23].…”
