bitertanol; chlorpyrifos-methyl; cucumbers; detection limit; diazinon; gas chromatography-mass spectrometry; malathion; markets; mixing; monitoring; pesticide residues; phosalone; polytetrafluoroethylene; silicon; solid phase microextraction; solvents; stainless steel
Abstract:
... A high-throughput solid-phase microextraction (SPME) on 96-well plate together with gas chromatography–mass spectrometry (GC–MS) was developed for the determination of some selected pesticides in cucumber samples. Pieces with the length of 1.0cm of silicon tubing were precisely prepared and then coated on the end part of stainless steel wires. The prepared fibers were positioned in a home-made pol ...

Subject:
air; derivatization; gas chromatography-mass spectrometry; ionization; methane; monitoring; oxidation; particulates; polycyclic aromatic hydrocarbons; smoke; solid phase extraction; temperature
Abstract:
... A sensitive method has been developed for the trace analysis of PAHs and their oxidation products (i.e., nitro-, oxy-, and hydroxy-PAHs) in air particulate matter (PM). Following PM extraction, PAHs, nitro-, oxy-, and hydroxy-PAHs were fractionated using solid phase extraction (SPE) based on their polarities. Gas chromatography–mass spectrometry (GC–MS) conditions were optimized, addressing inject ...

cetyltrimethylammonium bromide; desorption; detection limit; gas chromatography-mass spectrometry; micelles; microextraction; monitoring; multiresidue analysis; nanowires; pH; pesticides; polymers; river water; scanning electron microscopy; solvents; triazines
Abstract:
... A simple, rapid and sensitive method based on microextraction in packed syringe (MEPS), in combination with gas chromatography–mass spectrometry (GC–MS) was developed. Polyaniline (PANI) nanowires network was synthesized and used as sorbent of MEPS for the multiresidue determination of selected analytes from triazine, organochlrorine and organophosphorous pesticides in aqueous samples. The PANI na ...
