Environmentally friendly etching of stainless steel wire for plunger-in-needle liquid-phase microextraction of polycyclic aromatic hydrocarbons

Applications of Mass Spectrometry for Clinical Diagnostics: The Influence of Turnaround Time

“…Needles can also be used to facilitate sampling and ionization of analytes in clinical samples for in situ experiments for solid and liquid samples. , One such method, touch spray (TS), uses a needle probe to sample material and upon the addition of solvent and voltage, desorbs and transfers ions for MS analysis via field-induced droplet emission (Figure A,ii). Kerian et al described various applications that TS has been used for, such as tissue sampling, in vitro detection of bacteria, and trace detection of illicit drugs from various surfaces, and has shown that the rapid and reproducible sampling/ionization method has promise for further clinical diagnostic testing.…”

Polypyrrole/carbon nanotube coated stainless steel mesh as a novel sorbent

“…Therefore, sample preparation including clean-up, extraction, and preconcentration before analysis is necessary. Up to now, several extraction methods like liquid-phase microextraction (LPME), 7,8 dispersive solid-phase extraction (dSPE), [9][10][11][12] solid-phase microextraction (SPME), [13][14][15] and magnetic solid-phase extraction (MSPE) [16][17][18][19] have been used for the extraction of PAHs from various matrices.…”

Carbon Nanofibers-Based Nanoconfined Liquid Phase Filtration for the Rapid Removal of Chlorinated Pesticides from Ginseng Extracts

“…At present, holderassisted microliter liquid extraction has been widely demonstrated as a solvent-saving, time-saving, and simple technique. Various kinds of substrate-based solvent support phase extraction methods that employed materials like knitting wool, 16 stainless steel wire, 17 and melamine foam 18 have been explored, which can extract trace target compounds via loaded solvent. These studies highlighted the potential of flexible materials with a porous surface, which acts as an adsorbent filler or column packing for confining a minimal amount of solvent, and employed it to accurately separate ginsenosides and pesticides based on the distinguishable polarity difference.…”
