“…Charged nanoparticles from a solution are deposited onto a substrate using an electric field [24]. Single-walled carbon nanotube (SWCNT) [112][113][114] and multi-walled carbon nanotube (MWCNT) [115] coatings have been prepared on the surfaces of platinum and stainless steel wires, respectively. In EPD, adsorption takes place in the spaces between the nanotubes and amorphous carbon in a three-dimensional network of nanotubes [24].…”

“…Besides physical coating processes which are compatible with nearly all kinds of sorbent materials there is a clear trend towards procedures developed for specific components. Most attention in past years has been given to the application of nanomaterials [115,370]. Nanostructured MIP-based coatings will continue to be of particular interest.…”

Recent Developments and Applications of Solid Phase Microextraction (SPME) in Food and Environmental Analysis—A Review

Solid-phase microextraction (SPME) is a simple, sensitive, rapid and solvent-free technique for the extraction of analytes from gaseous, liquid and solid samples and takes a leading position among microextraction methods. Application of SPME in sample preparation has been increasing continuously over the last decade. It is most often used as an automatized fiber injection system coupled to chromatographic separation modules for the extraction of volatile and semivolatile organic compounds and also allows for the trace analysis of compounds in complex matrices. Since SPME was first introduced in the early 1990s, several modifications have been made to adapt the procedure to specific application requirements. More robust fiber assemblies and coatings with higher extraction efficiencies, selectivity and stability have been commercialized. Automation and on-line coupling to analytical instruments have been achieved in many applications and new derivatization strategies as well as improved calibration procedures have been developed to overcome existing limitations regarding quantitation. Furthermore, devices using tubes, needles or tips for extraction instead of a fiber have been designed. In the field of food analysis, SPME has been most often applied to fruit/vegetables, fats/oils, wine, meat products, dairy and OPEN ACCESS Chromatography 2015, 2 294 beverages whereas environmental applications focus on the analysis of air, water, soil and sediment samples.

“…The technique yielded limits of detection in the nanogram per liter range [15]. Another alternative is to enrich PAHs from the headspace (HS) above the water samples to a SPME fiber and finally analyze them with GC/MS or flame ionization detection (FID) [1,21,22].…”

“…Carbon-based nanomaterials (CNMs) have gained wide attention as sorbents in several analytical techniques, such as solidphase microextraction (SPME) fibers covered with nanomaterials [1][2][3][4], solid phase membrane tip extraction (SPMTE) [5], solid-phase extraction (SPE) [5][6][7][8][9], or as stationary phase in gas chromatography (GC) and liquid chromatography (LC) [10]. Superior material characteristics, such as high surface-to-volume ratios, high thermal stability, formation of non-covalent interactions with organic molecules, resulted in a steadily increasing application of CNM application in analytical chemistry [11].…”

Investigation of carbon-based nanomaterials as sorbents for headspace in-tube extraction of polycyclic aromatic hydrocarbons

Carbon-based nanomaterials (CNM) represent promising materials for the application as sorbents in micro- and other extraction devices. In this work, we investigate the applicability of five different CNM (multi-walled carbon nanotubes (MWCNTs), fullerenes, carboxylic acid functionalized multi-walled carbon nanotubes (MWCNTs-COOH), graphene platelets, and carbon nanohorns) for their performance on PAH extraction from the aqueous phase by headspace in-tube extraction (HS-ITEX). Optimal extraction parameters for HS-ITEX were determined using a Box-Behnken experimental design. From the extraction yield response, central point analysis, fullerenes showed the best extraction properties for the eight selected headspace compatible PAHs (naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, and pyrene). Fullerenes were used for a further method validation including the linear range, limit of detection, precision, as well as recovery. Finally, extraction yields were compared to a commercial material (Tenax GR), demonstrating that fullerene represents a better option as sorbent in ITEX for PAH analysis. Method detection limits for the PAH on fullerene ranged from 10 to 300 ng L, with recoveries between 45 and 103%.

“…However, due to the very hydrophobic nature, these carbon nanostructures strongly agglomerate in water hindering the PAH adsorption processes. Several attempts to fix the carbon nanostructures in different supports have been investigated such as graphene-based SPE disk [14], CNT supported on stainless steel fiber [15] and on a sol-gel material [16].…”
