Development and validation of a multi-residue method for determination of antimicrobial sulfonamides, macrolides and quinolones in Iranian feta cheese by SPE clean-up and LC-MS/MS

Design of a novel green bio-based organic–inorganic hybrid material for cost-effective and sustainable monitoring of antibiotic residues

“…SPE column packing is essential for effective enrichment and purification. 26 To date, many traditional and novel SPE packing methods have been widely used to enrich target analytes, including C18, 27 hydrophilic-lipophilic balance (HLB), 28,29 carbon nanotubes (CNTs), 30 mesoporous silica nanoparticles, 31 molecularly imprinted polymers (MIPs), 32 covalent organic frameworks (COFs), 33,34 metalorganic frameworks (MOFs), 35 etc. Although these adsorbents have largely solved the problem of MAC enrichment and separation in complex matrices, most of them are consumable adsorbents, the raw materials involved are difficult to regenerate and degrade and there are still some problems including the complicated preparation process, which involves consumption of many organic reagents, harsh reaction conditions, single interaction, susceptibility to interference by co-existing components, and limited recovery.…”

Developing a novel magnetic organic polymer for selective extraction and determination of 16 macrolides in water and honey samples

“…Various techniques have been proposed for the analysis of MALs such as capillary electrophoresis (CE), 25 immunogold chromatographic assay (IGCA), 26 thin-layer chromatography (TLC) 27 and liquid chromatography-tandem mass spectrometry (LC-MS/MS). 28,29 Among these methods, LC-MS/MS is the most popular technique due to its sensitivity, specicity and ability. 30 Up to now, the technique has been applied for the determination of different samples.…”
